Question

heterozygous gene pair are always dominant to their phenotype
give reason ​

Answer 1

Explanation:

If two alleles of a given gene are identical, the organism is called a homozygote and is said to be homozygous with respect to that gene; if instead the two alleles are different, the organism is a heterozygote and is heterozygous. ... At heterozygous gene loci, the two alleles interact to produce the phenotype.
