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.

what subject is this

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
