7. Black fur (B) in pigs is dominate over white fur (b).
Find the probability of a pig in the offspring as
being heterozygous, using parents Bb x BB
a. 0%
b. 25%
C. 50%
d. 75%
e. 100%

C). 50%

Explanation: A cross between Bb and BB will produce four offsprings. Bb x BB = BB, BB, Bb and Bb.

From the result of the above cross, two offsprings are homozygous (BB) while two offsprings are heterozygous (Bb). Being heterozygous means having one dominant allele and one recessive allele.

The probability of an offspring being heterozygous is 2/4 x 100 = 50%. This means that there is 50% chance of an offspring being heterozygous.
