There are two parts to this definition ... PhenotypeThis is the "outward, physical manifestation" of the organism. These are the physical parts, the sum of the atoms, molecules, macromolecules, cells, structures, metabolism, energy utilization, tissues, organs, reflexes and behaviors; anything that is part of the observable structure, function or behavior of a living organism.\n\nGenotypeThis is the "internally coded, inheritable information" carried by all living organisms. This stored information is used as a "blueprint" or set of instructions for building and maintaining a living creature. These instructions are found within almost all cells (the "internal" part), they are written in a coded language (the genetic code), they are copied at the time of cell division or reproduction and are passed from one generation to the next ("inheritable"). These instructions are intimately involved with all aspects of the life of a cell or an organism. They control everything from the formation of protein macromolecules, to the regulation of metabolism and synthesis.

Genotype are the genes present in the DNA of an organism that determine that organism's traits. Each genotype is referenced with two similar letters - one capital one lower case. This means that there are three possible combinations, e.g. BB or Bb or bb. The capital letter represents the dominant gene and the lowercase the recessive gene. So each offspring gets a gene which is a combination of those passed down from its parents. By way of example, lets look at the size of your nose. Your Dad has a big nose with genotype Bb and your Mum has a small nose with genotype bb. If your Dad passes down the B and your Mum the b then you will have a big nose (Bb) because the B will dominate the b. But if they both pass down the b (bb) then you will have a small nose. If you get bb then that is called homosygous (pure) genotype and if you get Bb that is called hetrozygous (hybrid) genotype. The reason it is sometimes possible for a child to look nothing like either of their parents is that if both parents are hybrid genotypes (eg. in the nose example both are Bb and therefore both have big noses) all three combinations (BB, Bb or bb) are possible and you may get the bb and have a small nose...

Your genotype determines your blood type before your born. There are three alleles or versions of the blood type gene: A, B, and O. Since everybody has two copies of these genes, there are six possible combinations; AA, BB, OO, AB, AO, and BO. In addition to the proteins (agglutinogens) existing on your red blood cells, other genes make proteins called agglutinins (a-GLOO-tin-ins) that circulate in your blood plasma. Agglutinins are responsible for ensuring that only the blood cells of your blood type exist in your body. People who have an AA genotype are said to have type A blood because the agglutinogen on their red blood cells has the enzyme activity associated with the A allele. It is important to recognize that people with the AO genotype also have the enzyme activity associated with the A allele, so they are also said to have type A blood. People with the BB and the BO genotypes are said to have type B blood. People who have the AB genotype have the enzyme activity associated with both the A and B alleles. These people have no agglutinins in their blood plasma.  In the case of blood type, both the AA and AO genotypes cause individuals to display the A blood type phenotype. Similarly, both the BB and BO genotypes cause individuals to display the B blood type phenotype. Individuals who are phenotypically type O or type AB have only one possible genotype, OO and AB, respectively. In different parts of the world, the fraction of individuals with blood type A, B, O, or AB differs. The frequency with which blood types are observed is determined by the frequency with which the three alleles of the ABO gene are found in different parts of the world (allele frequency). Variation in the allele frequency at the ABO gene reflects the social tendency of populations to marry and reproduce within a national, regional, or ethnic group. As people throughout the world intermingle to a greater extent, the distribution of the different blood types will become more uniform throughout the world. Hopefully that helps a bit!

Codegirl gave a great answer, although she left out the possibility of your husband being AB and giving an A to make your child AA.  All I'd add is that you have to understand the difference between phenotype (which is the expressed form) versus the genotype (with is the combination of genes).  When you and your baby were typed, they only look at the phenotype, not the genotype.\n\nA person tested as A can be genotypically AA (A from both parents) or AO (A from one parent; O, which is recessive, from the other).\nA person tested as B can likewise be BB (B from both parents) or BO (B from one parent, O from the other).\nA person tested as AB must be genotypically AB, getting one from each parent.\nA person taht is tested as O must likewise be OO, getting O from each parent.\n\nA parent gives one of their two alleles to their child.  If you are AB, you could give your child either A or B.  Since their are two possible combinations of alleles that make A (AA and AO), the father might have contributed either an A or an O.  So the only thing known for certain about the father's genotype is that he is NOT BB.  He could be either AA, AB, or AO (and contributing an A to make your child genotypically AA), or he could be either BO, OO or AO (and contributed an O to make your child genotypically AO).  But phenotypically, the father could be anything: A, B, AB, or O.

The genetic composition--the genotype--is what determines the phenotype of an individual. The phenotype is how the genes are expressed physically, thus it includes what it looks like.

hehe. Something is amiss.  \nO is recessive. A and B are codominate.\nTo be true O, your genotype is OO.\nTo be B, your genotype is BB or BO.\nTo be A, your genotype is AA or AO.\nTo be AB, your genotype is AB.\nSo one of your parents have to have B allelle.  If either of your parents are OB (then in reality one of your parents is blood type B not O.), then it is possible that you are blood type B.\n\nIf not, well, your patients raised you and you consider them your parents.  Does it really matter that one of your parent is not you biological parent.  Talk to them.  Be patient and they may explain things to you when you get older.

Alleles are different 'forms' of the same gene.\n\nFor example, there are three alleles of the gene for blood groups; alleles A, B and O.\n\nIn diploid organisms like ourselves we have two complete sets of genes, so there are various combinations of alleles. One allele is inherited from the mother and one from the father.\nAA - blood group A\nAO - blood group A (because A is dominant to O)\nBB - group B\nBO - group B (B dominant to O)\nAB - group AB (alleles are codominant - equal dominance)\nOO - group O\n\nGeneologically, we can follow the inheritance of various characteristics (determined by alleles) and similarly blood groups can be used to eliminate or confirm parentage.\n\nThe 'classic' geneological example is the family tree of Queen Victoria of Great Britain. This follows the inheritance of the sex-linked gene for haemophilia.

Homozygous genotype is when youre alleles are AA, Homozygous means the same-- and the capital letters represent dominant alleles.\nits dominant because only DOMINANT alleles are represented (AA)\n\nHeterozygous genotype's occur when you have one dominant allele and one recessive.. like Aa, because lower case is recessive.\n\nif the heterozygous genotype is recessive.. the genotype will not be seen in the phenotype. \nIf it is dominant .. the uppercase letter (the dominant allele) will be shown in the phenotype.\n\nUsually a heterozygous genotype is recessive- but it depends on the first filial generation\n\nthis is all easier to explain on a punnets sqaure..email me if you have more questions! emo4@uakron.edu

i took biology way back ..lets see...8 years back, :)\nbut this is what i found on a website...\n\n\nProblem 5: Dash Technique\n\nRecall that a phenotype is the outward expression of an organism's genes or genotype. For example, type A blood (the phenotype) is the expression of the genes, AA or AO (the genotype).\n\nNote that we do not know for certain whether the correct genotype is actually AA or AO since both genotypes will produce the type A phenotype. For this reason, when solving many blood type genetics problems we let a "dash" represent the uncertain gene In the example of the type A blood, we could represent the genotype as A-.\n\nTheres a sample problem that the website has solved!\n\nHappy genetics..long live Mendel..but hes dead..isnt he? that was dumb!

If this is a true genomic sequence, you can only start at a start codon, which is ATG.\n\nBut, this appears to be a template sequence, so we'll do transcription now:\n\nThe corresponding mRNA is:\nAUG AAU GGC UCU AAG AAG AAA UAG\n\nAUG is a valid start codon.  And by the way, that's methionine (Met or M).\n\nNow the rest:\nAAU=Asparagine (Asn or N)\nGGC=Glycine (Gly or G)\nUCU=Serine (Ser or S)\nAAG=Lysine (Lys or K)\nAAG=Lysine again (Lys or K)\nAAA=Lysine again (Lys or K)\nUAG=Stop codon\n\nSo the end sequence is Met-Asn-Gly-Ser-Lys-Lys-Lys, or in single-letters, MNGSKKK.

In regards to what? Blood? Sex typing? Genes? Cars? You need to be more specific!!
