Kucing Berwarna! What Color Fur Will They Have?

Let's break down the possibilities for the offspring's coat colors:

a) All with black fur:

For all eight kittens to have black fur, they must have either the BB or Bb alleles. The probability of black fur is 3/4.

b) Five with black fur and three with white fur:

To have 5 kittens with black fur and 3 with white fur, the probability of black fur is 3/4 and the probability of white fur is 1/4. Therefore, the probability of 5 black kittens is 3/4 * 5.

c) At least three kittens having white fur:

For at least three kittens to have white fur, we need to consider the probabilities of white fur (1/4) and black fur (3/4) for the remaining kittens.

d) The firstborn kitten with white fur, and among the remaining seven kittens, three with black fur and four with white fur:

If the firstborn kitten has white fur, it must have the bb allele. For the remaining seven kittens, the probabilities are the same as in the previous cases.

In conclusion, the probability of different combinations of offspring in a litter of eight kittens with two heterozygous black parents can be calculated based on the genetic inheritance of coat color. The dominant black fur allele and recessive white fur allele play a significant role in determining the coat colors of the kittens.
