Detailed explanation-1: -Heterozygous refers to having different alleles for a particular trait. If the two versions are different, you have a heterozygous genotype for that gene. The relationship between the two alleles affects which traits are expressed.
Detailed explanation-2: -The term “heterozygous” also refers to a pair of alleles. Unlike homozygous, being heterozygous means you have two different alleles. You inherited a different version from each parent. In a heterozygous genotype, the dominant allele overrules the recessive one.
Detailed explanation-3: -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.
