Answer:

b) 0.30

Explanation:

An individual who is heterozygous for two linked genes (with alleles A, a and B, b)

i.e Aa & Bb × ab/ab

This cross produce the following offspring :

14 AB/ab  

36 Ab/ab  

34 aB/ab  

16 ab/ab

Now, the purpose of these calculation is to determine how close together on a gene (gene mapping) these recombinants are.

First, we need to determine the linked gene for the parental chromosomal configurations which are (Aa & Bb × ab/ab) and the recombinant configurations in the offspring which are ( AB/ab & ab/ab). This allows for the calculation of the recombinant frequency; and it is given by:  

= \frac{number of recombinant frequency}{total number of offspring}

=\frac{14+16}{14+36+34+16}

= \frac{30}{100}

= 0.3
