Quizplus · Accepted Answer

An individual who has two different alleles for a trait is called heterozygous. Haploid refers to having half the number of chromosomes (one set) in the nucleus of a cell. Homozygous refers to having two identical alleles for a particular gene. Isozygous is not a commonly used term in genetics. True-breeding refers to a homozygous individual that always produces offspring with the same phenotype.
