Question
Chapter 12.3, Problem 3R
Summary Introduction
To analyze:
The percentage of offspring, which will be deaf in a parental cross between aaBb and Aabb, where the dominant allele A is essential for hearing and the dominant allele B leads to deafness irrespective of the other genes present.
Introduction:
The genes A and B are present on different chromosomes so they will show independent assortment. The recessive alleles will not be expressed in the presence of their dominant alleles, meaning that the dominant allele will show its

In cattle, coat color is inherited in a co-dominant fashion. Homozygous C R C R produces red coat,homozygous C W C W produces white coat, and the heterozygous C R C W produces roan-colored coat.What is the probability of having a roan-coated offspring in a cross between a white-coated cattle anda roan-coated cattle?
In humans, brown eyes (B) are dominant over blue. A brown eyed man marries a blue-eyed (b) woman and they have three children two of whom are brown-eyed and one of whom is blue-eyed.
