In human beings blood group is determined by four alleles IA, IB, Ii A gene contain only two alleles either IA IA-- result A group IA IB--- result AB group- because of the phenomenon of co-dominance IA Ii---- result A group- A is dominant over i IBIi--- result B group- B is dominant over i IB IB-- result B group Ii Ii-- result O group dr.sreejithnamboodiri@gmaill.com

How are multiple alleles different from polygenic traits?
Multiple alleles are genes that have more than two alleles. An example of this would be blood types, with ABO as three separate alleles.Polygenic traits are traits whose phenotype rely on alleles from different genes. An example of this would be hair type, which relies on genes from different parts of chromosomes.The main difference is that multiple alleles are genes with 3 or more alleles; polygenic traits do not necessarily have more alleles, but they rely on on multiple genes.
What is the definition of alleles?
An allele is one possible coding sequence that can be in a gene. Often one gene will have several different possible alleles (e.g. for hair color). Alleles are now understood to be alternative DNA sequences at the same physical locus, which may or may not result in different traits.
How is the inheritance of traits controlled in organisms?
Individual alleles control the inheritance of traits. Some alleles are dominant, while others recessive.
The law of independent assortment states the the inheritance of alleles for one trait is not affected by the inheritance of alleles for a different trait if the genes for the traits are on?
separate chromosomes
How are dominant and recessive genes related?
Dominate them. Recessive alleles do not show in your phenotype unless you have two of the same recessive allele. But if you inherit one dominant and one recessive, it is the dominant that always shows in your phenotype.
What allows humans to have different traits?
Different alleles allow people to have different traits from each other.
What will a population with different alleles have?
A population with different alleles will have traits
How does the range of phenotypes for single gene traits different from the range for polygenic traits?
ABO Single gene trait blood group alleles on humans. That is the variation, not much, and not much recombination. 3! = 6. There is posited to be at least 7 alleles for height, which is a polygenic trait. Hypothetical alleles, SMYDKECV 7! = 5040 different combinations of alleles in height polygenic traits.
What causes a wide range of phenotypes for some traits?
Some traits, such as eye color and hair color, have multiple alleles that control different aspects of the phenotype. Because there are multiple different possible combinations of alleles, you get a wide range of phenotypes.
What is the name for different forms of traits?
alleles
Why do population have variations in certain traits?
For one thing, different individuals have different alleles.

What allows these mice to have different traits from each other?
The mice have different alleles or something
Two brothers inherit different sets of alleles from their parents What effect will this have?
They will have different traits.
What traits are controled by a gene with multiple alleles?
Some of the human traits determined by multiple alleles would be hair color, hair texture, eye color, built, physical structures, etc. One notable and most common example of multiple alleles in humans would be of the blood groups.
