Alleles
Alleles are genes that exist in multiple forms.
Some alternative forms of genes include alleles, which are different versions of the same gene, and gene duplications, where a gene is copied multiple times within an organism's genome. Additionally, genes can undergo mutations that lead to different forms or variants known as gene variants or polymorphisms.
this makes no scientific sense. A gene (which determines a phenotypic trait) can only contain 2 alleles. However codominace allows for multiple alleles to be chosen from, but only 2 picked for a gene. Also, if multiple genes determine a phenotypic trait that's polygenic inheritance.
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.
If you are a teenager and have Multiple Sclerosis in your genes you can read books to enjoyment.
Mendel found that certain forms of genes were dominant to other forms of genes. This means that when an organism has two different forms of a gene, one form will be expressed over the other in determining the trait it controls.
Alleles are different forms of the same gene. For example, if eye colour was coded for by just one gene, blue eyes would be one allele and green eyes would be another. Different genes, however, code for different things, so you might have a gene for eye colour and another for hair colour.
Alleles are forms of genes for a trait.
The vitamin E "tocopherol" exists in eight various forms.
Alleles are different forms for a trait
different form of genes are called allele
Variation exists within the genes of every population or species as the result of natural selection. The other reason is due to neutrality of mutations.
