Question

a population of rabbits follows the typical pattern of inheritance and the law of dominance for fur color: b is the allele for brown fur and b is the allele for white fur. in a population of rabbits 160 bunnies are born. how many bunnies should be white, according to the punnett square?
a 40
b 80
c 50
d 160

Explanation:

Step1: Analyze the Punnett square

From the Punnett square, the genotypic ratio is \( BB:Bb:bb = 1:2:1 \). Since \( B \) (brown) is dominant over \( b \) (white), only \( bb \) rabbits have white fur. The proportion of \( bb \) is \( \frac{1}{4} \).

Step2: Calculate the number of white - furred bunnies

Given there are \( 160 \) bunnies born. The number of white - furred bunnies \( n=160\times\frac{1}{4} \).

$$n = 40$$

Answer:

A. 40
