Question

Quizplus · Accepted Answer

When an individual allele affects more than one trait, it is called pleiotropy. This means that a single gene can have multiple effects on the phenotype of an organism. It is important to note that this is different from epistasis, which refers to the interaction between two or more genes that affects a single trait. Recessive and dominant refer to the expression of traits in relation to the presence or absence of certain alleles, and homozygotic refers to having two identical alleles for a particular gene.
