heterozygous

|
Hybrid

|
Pheotype

DNA

Explanation:
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: -If an organism has two copies of the same allele, for example AA or aa, it is homozygous for that trait. If the organism has one copy of two different alleles, for example Aa, it is heterozygous.
Detailed explanation-3: -The expected phenotypic ratio for a cross between two individuals that are heterozygous for a given trait is 3:1 for the dominant phenotype compared to the recessive phenotype.
