Question

Imagine a cross between a man and a woman having the following genotypes: 

 

Genotype of the Husband                                                                         Genotype of the Wife

 

                               Aa bb Dd Gg Hh RR Tt                  X                  Aa Bb Dd gg Hh Rr Tt

Suppose, that the A allele exhibited incomplete dominance over the a allele and the T allele exhibited incomplete dominance over the t allele. In that instance, how many different phenotypes would be possible among the offspring of this same couple?

Expert Solution
Step 1

Introduction

A gene is consisting of a pair of alleles/ factors and can be dominant or recessive. The dominant allele is represented by a capital letter for example (Y) and the recessive is represented as a small letter for example (y). In normal conditions such as in Complete dominance, the Dominant allele suppresses the effect of another allele which is recessive in homozygous conditions as well as in heterozygous conditions while the recessive allele can only show its effect in the absence of the dominant allele in homozygous conditions only. However, the Incomplete dominance scenario is quite different.
