Question

In addition to the allelic pair determining pattern baldness in man (B,b), consider early baldness to be due to another autosomal allele (E) on a different pair of chromosomes and also dominant in males but recessive in females. The phenotype for ee may be late or nonbaldness depending on sex and the genotype for B, b alleles. Two doubly heterozygous persons marry.

What is the phenotype of the male parent?
What is the phenotype of the female parent?

Give the phenotypic ratio expected among female children of couples such as this one. Show corresponding genotypes for each phenotype mentioned in your phenotypic ratio.

Expert Solution

Step 1

Introduction

Inheritance is referred to as the transfer of character from parents to offspring and this occurs via the transfer of genes in the form of gametes. A zygote is formed by the fusion of male and female gametes which carries male and female genes respectively.

Dominant genes are those genes that express themselves in the offspring in either homozygous or recessive conditions by suppressing the effect of a recessive gene. The recessive gene only expresses itself when it is present in a homozygous condition.
