an individual that is heterozygous at two genetic zygous

|
|
a trait controlled by a gene on a sex chromosome

a mating in which the homozygous recessive individuals of unknown genotype that have the dominant phenotype

None of the above

Detailed explanation-1: -An individual who is heterozygous for two genes is called a dihybrid. A dihybrid cross is when you mate two dihybrids together. This cross results in a 9:3:3:1 ratio of offspring. This ratio is for offspring phenotype.
Detailed explanation-2: -A dihybrid cross describes a mating experiment between two organisms that are identically hybrid for two traits. A hybrid organism is one that is heterozygous, which means that is carries two different alleles at a particular genetic position, or locus.
Detailed explanation-3: -A dihybrid cross is a breeding experiment between two organisms which are identical hybrids for two traits. In other words, a dihybrid cross is a cross between two organisms, with both being heterozygous for two different traits. The individuals in this type of trait are homozygous for a specific trait.
Detailed explanation-4: -heterozygous. a genotype consisting of two different alleles of a gene for a particular trait (Aa). Individuals who are heterozygous for a trait are referred to as heterozygotes.
