Question

5c. Two parents, a heterozygous normal female and a male who is

Answer 1

Answer and Explanation:

We can assume that being colorblind is a recessive trait.

That means the father has a genotype of both lowercase letters, denoted as bb.

Let's make a chart.

- The Father's Genotype is bb

- The Mother's Genotype is Bb (Because she is heterozygous, which means she has one Dominant trait (B) and one recessive trait (r))

     b               b  

B|   Bb   |   Bb     |

b|   bb    |   bb     |

We get 50% of the offspring to be colorblind, and 50% of the offspring to have normal color vision.

That means the expected percentage is 50%.

(Don't look too much into the capitalized MALE, its just there to throw you off guard and mess you up)
