Question

Quizplus · Accepted Answer

For every trait expressed in a sexually reproducing organism, there are at least two alternative versions of a gene, called alleles.
An allele is a variant form of a given gene. Sometimes, different alleles can result in different observable phenotypic traits, such as different pigmentation.
If the pair of chromosomes have the same alleles (such as GG or gg), then the organism is said to be homozygous for that characteristic. If the alleles are different (such as Gg), then the organism is said to be heterozygous.
