multiple allelic compare with polygenic inheritance?
450321
Multiple alleles inheritance is a gene that has more than two alleles such as the gene for the ABO blood group. Two alleles IA and IB are codominant and i is recessive. \nPolygenic inheritance is a characteristic that is controlled by more than one gene, each one having two alleles such as hair color, eye color, skin color etc.

Very simply put, dominance and recessiveness are characteristics of genes.\n\nA dominant gene is expressed (shows up visibly in the offspring) when only one copy of the gene is present, on one chromosome from one parent. Let's say Tallness is a Dominant gene. If you have ONE tall parent, and get ONE copy of the Tall gene, you will probably be tall. If your tall parent was the son or daughter of a TALL and a SHORT person, they may only have ONE copy of that gene. If you get both SHORT chromosomes from Mom and DAD, you will NOT be tall. So you have 50 to 100 chance of being tall with a Dominant gene.\n\nNow, let's take the gene for BLUE eyes. It is recessive. You need TWO copies of this gene to get blue eyes. If Mom has blue eyes and Dad has blue eyes, and you get copies of both blue eye genes, you will have blue eyes. But if Mom has blue eyes, and Dad has brown eyes, you might end up with Brown eyes. Don't that make your blue eyes brown, so to speak.\n\nBUT..if Dad's mom had blue eyes and Dad's dad brown (your grandparents) and if Dad has one blue eye gene and one brown eye gene and has brown eyes AND if your Mom still has those blue peepers, you have a 1/4 chance of ending up with one blue eyed gene from AND a blue eyed gene from Dad and you will also have blue eyes like your Mum. Don't that make your brown eyes...blue?

One of each pair is derived from either parents. Also due to the diploid nature of chromosomes genotypes as homozygous dominant, homozygous recessive and heterozygous can be found. Thus a recessive character can be avoided to the maximum.

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.

I'm a twin, and we do have similar traits, we think on the same wavelength, but our personalities differ, i am outgoing, my brother is more laid back. So, i think it's in the genes.i'm like my dad, he's like my mum.

Assuming Black is dominant (B) and Albino is recessive (b)\n\nThe first cross produced all black\nbb x BB\n---B-----B\nb Bb----Bb\nb Bb----Bb\nFrom here, you can see that all the offsprint have one dominant Black gene, so they will all be black.\n\n\nThe second cross had about half albino\nbb x Bb\n---B-------b\nb  Bb-----bb\nb  Bb-----bb\nFrom this one, you can see that half of the offspring are homozygous recessive bb, and are albino.\n\n(Ignore the ---- in hte cross, they don't mean anything, they are just for spacing because yahoo deletes multiple spaces)

A polymorphism.  Generally, for a given gene sequence there are numerous variants  (known as alleles) that differ from one another at one or more nucleotides.  These nucleotide variations may affect a gene's expression at the mRNA level or function at the protein level (or not).\n\nSome gene variants are known to be clinically significant and genetic tests for single nucleotide polymorphisms (SNPs) are now done regularly to test for these alleles when a patient has a family history for a particular disease.\n\n"SNPs ... can help determine the likelihood that someone will develop a particular disease. One of the genes associated with Alzheimer's, apolipoprotein E or ApoE, is a good example of how SNPs affect disease development. This gene contains two SNPs that result in three possible alleles for this gene: E2, E3, and E4. Each allele differs by one DNA base, and the protein product of each gene differs by one amino acid. Each individual inherits one maternal copy of ApoE and one paternal copy of ApoE. Research has shown that an individual who inherits at least one E4 allele will have a greater chance of getting Alzheimer's. Apparently, the change of one amino acid in the E4 protein alters its structure and function enough to make disease development more likely. Inheriting the E2 allele, on the other hand, seems to indicate that an individual is less likely to develop Alzheimer's."  {cited from web site below}

A, they will have the same phenotype, but not necessarily the same phenotype.  If you are basing this question on simpler Mendelian genetics you could have both parents with trait A, resulting from Aa (parent 1) and Aa (parent 2), but the offspring genotype is AA.  They all appear the same, but they aren't on the genetic level.

It is most definetly a recessive gfene. I know this because so few people posses this trait. However there is a possibility of it occuring. Actually the small big toe depends not just on one allele but several alleles at several loci but in the end all sucha lleles are recessive and do not give heterozygote advantage

John is actually incorrect... our characteristics are not governed solely on out genes, there are many factors that are involved.\n\nSome characteristics such as hair colour and eye colour are govered by our genes, but we can actually appear differently depending on how we developed in the foetal stage of development, as well as injuries we may sustain, what we eat, how we live, and psycological responses that lead to hormonal responses (or vice versa). All of these can change markedly our characteristics.\n\nSome simple examples include 'wide feet', spinal malformation (eg. muscular scoliosis), asthma, and many more. Note that these may be influenced by genetics, but having the gene does not mean you get the characteristic.\n\nConsider that two identical twins can actually be told apart becasue one is often slightly taller, or slightly fatter or has different characteristics, however their genes are the same.\n\nConsidering that the environment in the womb during pregnancy can change a human's characteristics quite markedly as it can also change hormonal development, then we must realise that if you were to be cloned then your clone may look very different from you... although you will most likely look similar enough to look like siblings.

This is about as close as I can get you. Good luck\nhttp://www.genetree.com/product/dna-test-collection.asp

EEEEH. I'm not really good with this mumbojumbo stuff but here is a site on genotypes and stuff. -> http://janis7hepc.com/Genotypes.htm <-

There is no "versus". Mendelian Genetics explained heredity years before when people had funny ideas about inheritance (there was one which said only the father contributed to the children's character and another which said it was the mum!). Biotechnology is using this knowledge as well as knowledge from diverse fields such as Chemistry, Physics, Statistics etc. to modify nature a little for man's benefit. Why the  "versus" question? Both work in tandem.
