Solutions For An Introduction to Genetic Analysis Chapter 17 Problem 31P

Step-by-Step Solution

Solution 1

A trisomic of the genotype can produce a gamete of genotype a. The meiotic products of trisomic with genotype are as follows:

Here, three equally likely segregations would have taken place. Thus, the three gametes formed would be as follows:

A

Aa

AA

The probability of the gametes would be as follows:

• The genotype would be

• The genotype would be

• The genotype would be

• The genotype would be

Hence, the occurrence of a gamete with the genotype would be of the total number of gametes.
