It is important to consider whether the sample size selected by the Environmental Genome Project will provide sufficient power to discover most alleles relevant to gene-environment interactions. Samuel Wilson
Apart from mutant versions of genes selected in antiquity during domestication, there has been more recent deliberate selection of alleles that affect growth characteristics. Source: Internet
A gene with more than two alleles is said to have multiple alleles. Source: Internet
An organism that has two different alleles for a gene is said be heterozygous for that gene (and is called a heterozygote). Source: Internet
An organism that has two identical alleles for a gene is said to be homozygous for that gene (and is called a homozygote). Source: Internet
Another observation is that traits or alleles that vary from one group to another do not vary at the same rate. Source: Internet
