Question

I’m looking at problem 1C) I’m getting 64 by multiplying the potential male and female possibilities and dividing by 2 equaling to 64, but this practice exam has 54. Name: AnSc 1101 Introductory Animal Science Genetics Exam (2018 Check one! Post my grades by the last 4 digits of my student 1.D. number. Post my grades by this number Do not post my grades. Short answer/problem solving: 1. A male Aa Bb cc Dd ee is mated to a female that is Aa Bb CC Dd Ee. 8 a) how many possible genetic combinations in the spem? 16 b) how many possible genetic combinations in the eggs? 54 c) how many possible genetic combinations in the offspring? ? Match the gene action illustrated by the following numbers.

Explanation / Answer

Different types of gametes

The cross between AaBbccDdee X AaBbCCDdEe will produce following different types of gametes

For locus 1: AA Aa aa= 3

For locus 2: BB Bb bb= 3

For locus 3: Cc= 1

For locus 4: DD Dd dd = 3

For locus 5: Ee ee = 2

Thus, possible genetic combinations= 3x3x1x3x2= 54.
