Question

Quizplus · Accepted Answer

A diploid organism has two sets of chromosomes, but it does not specify whether those chromosomes carry the same allele or different alleles of a given gene. Heterozygous means that the organism has two different alleles of a particular gene, which is the case when an individual inherits one allele from each parent. Dizygous is not a commonly used term in genetics and does not relate to having two different alleles of a given gene. Merozygous refers to a bacterial cell that has had some genetic material removed and thus has a partial diploid state, which also does not relate to having two different alleles of a given gene. Heteromorphic describes individuals with different physical traits, but it does not necessarily relate to their genetic makeup.
