#11.Use the following information to answer the next two questions.

In mice, black fur (W) is dominant over white fur (w), and black eyes are dominant (R) over red eyes (r).

A male mouse with black fur and black eyes mated with a female mouse with white fur and red eyes. Out of 64 offspring, 30 had black fur and black eyes, and 34 had white fur and black eyes.

What is the genotype of the male parental mouse?

#12. use the information form question 11 to help solve this question. A male mouse heterozygous for both fur and eye colour mated with a female mouse heterozygous for both traits.

Out of 64 offspring, how many mice can be expected to be heterozygous for both fur and eye colour?
Select one:
a. 4
b. 48
c. 12
d. 36
e. 16
f. 1
Heterozygous means different and homozygous means the same. So wouldn't the answer be b 48 because 48 mice would have both different fur and eye colour.
