hey im doing this in class too. the phenotype is black because the the black is dominant. whatever the capital letter is, that is the dominant trait. if the genotypes were: BB or Bb, the phentype is still dominant. The only difference is that BB is a homozygous trait; meaning that homosygous trait is the same trait or identical trait. Bb is heterozygus trait meaning that it is two different traits.

Traits that are genetically based can be inherited either dominantly or recessively.  Traits refer to what we call a phenotype, and the specific combination of DNA leading to this phenotype we call the genotype.  As an example, let's consider a pea plant which has two descrete and separate heights: large and small.  To analyze the inheritance of plant height, you first establish small or large plants that breed true, for example, crossing a large plant with a large plant always breeds large plants.  Then, you breed true-breeding large and small plants together.  If large is dominant (and small recessive), the offspring will all be large, because the 'large' genotype is dominanting the 'small' genotype.  If small is dominant the offspring are small.  Dominant and recessive are mutually exclusive classifications of the genotype.  \n\nTo extend this analysis further, you can cross that large x small generation (called the F1 generation) together (this is called an intercross).  Let's say large is dominant and the F1 plants are all large.  Intercrossing the F1 will lead to both small and large offspring.  If only one gene is responsible for the plant height, then the ratio of large:small plants will be 3:1.  \n\nThis is the essence of genetics, the linkage of genes to discrete, measurable characteristics.  Not all characteristics are genetic, and for complex issues such as diseases many genes play a role.  But the essence is still the same.  It works because for every person or plant, you receive one genome set from your mother and one genome set from your father, thus the inheritable characteristics you develop can then be passed down to the next generation.

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...

Sure, I do.\n\nStep one: identify your question.\n\nStep two: figure out as much as you can about the phenotypes of the parents and the offspring\n\nStep three: some of the genotypes may be obvious from the phenotypes. \n\nStep four: figure out what kind of gametes an individual can make. \n\nStep five: Are you in control of any crosses? Or are the crosses already done? \n\nStep six: If there is any need, do Punnett squares of those crosses you can't just figure out by looking.

Ok, here's how it works. It seems that you need genotypes. A homozygous trait is a trait that is both dominant and recessive. Therefore, the organism possesses the dominant trait. A heterozygous genotype is always dominant (dominant is dominant over recessive). For example, brown hair (B) is dominant over blond hair (b). a heterozygous person will be Hh, and will have brown hair even though both alleles are present.

1. at a basic level, genetic traits are determined ultimately by the DNA sequence. Differences in the DNA sequence between individuals may result in differences in traits. Differences in the DNA sequence of a gene are known as alleles. \n\n2. The traits determine the characteristics of an organism because the DNA sequence manifests itself as a protein. DNA is transcribed into RNA which is then processed (spliced) into mRNA. mRNA is translated at the ribosome (through the use of tRNA which brings in amino acids) into a polypeptide or protein. Differences in protein sequence may alter protein function thus resulting in an altered trait, also known as a phenotype.

3. populations that have the potential to interbreed and produce fertile offspring.\n\nnumber 1 could be a taxon, number 2 could be a population, 4 is allopatric organisms, and 5 is organisms in the same niche.\n\nof course, 3 gets fuzzy as soon as you want to talk about organisms with the ability to clone themselves, like bacteria... but generally the definition is a group of organisms that have the ability to interbreed and produce fertile offspring.

1) phenotype: \nPhenotype comes from Greek phainein, “to show.” It describes a person’s physical and biochemical expression of his or her genotype as well as a person’s physical manifestation of various environmental influences.

As I recall, the map unit is a 1% chance that two genes will sort independently. So, 13% will be al/+ phenotype, 13% dp/+, 37% are al/dp, and the other 37% are wildtype. I think... definitely check this before you accept it as true.

first all blood has 3 genes a,b,o.  A and B are both dominant while o is recessive.  A person with A phenotype blood can have a genotype of AA or AO.  Same with the B phenotype blood except only with B.  AB phenotype is the same as the genotype AB and same goes for O.  OO phenotype can only be seen as OO genotype.  When people do the nasty and mate each one type is paired with another.  For example an AO phenotype person and an B0 phenotype person can have a babies as AB,AO,BO,OO.  The punnet square all depends on two peoples blood type and the possibilities of the childs when they mate, you cannot make a square of an individual.

An example of a third variable can be seen in the following  scenario:\n\nA correlation study between warm parenting and better adjusted children.\n\nWarm parenting = variable X\nWell adjusted child = Variable Y\n\nDoes X cause Y?\nDoes Y cause X?\n\nA third variable problem occurs when there is a possibilty that neither variable X or Y have a casual effect on the other and that they are in fact a result of a third variable (variable Z). Variable Z could be any number of things that influences both variable X and Y. An example of this could be a genetic predisposition that causes a parent to be warmer in a nature or a child to be better adjusted.\n\nPut into simple terms the "third variable problem" is when Z is responsible for what looks like a relation between X and Y.

A)\n\nAs far as pod size, at least one parent must be homozygous for H, since all the offspring have one pod.  The other parent coudl have any genotype for that gene\n\nThe leaf shape is showing the 3:1 ratio characteristic of a dihybrind cross.  So both parents must be het at the leaf locus.\n\nB) is similar, since all the offspring have 3 pods, the parents must be homozygous for that recessive allele.  The other parent coudl have any genotype for that gene.\n\nThe 3:1 ratio of leaf shape shows that the parents must again both be het for the leaf shape locus.\n\nC)  If all the offspring show the dominant pheontype, one parent must be homozygous for the pod number, and one must be homozygous for the leaf shape.  Either the same parent is homozygous for both, or each is homozygous for one trait.  Again, if one parent is homozygous for a gene, the other parent coudl have any genotype at that locus.\n\nD)  The ratio of one-pod/3-pod is again, 3:1, so both parents must be het for that gene.  Since half the offspring have the dominant leaf shape, and half have the recessive leaf shape, that means that one parent must be homozygous for the recessive allel, and the other must be het.\n\ne) The ratio of one-pod/3-pod is closest to 3:1, so both parents must be het for that gene.  again, the ration is leaf shapes is closest to 1:1, so one parent must be homozygous recessive, the other het.\n\nBut the ratios aren't quite right, there's something non-Mendelian affecting the offspring here.
