The breeder is surprised when all of the offspring from this cross are rabbits with a brown and white coat. Which genetic principle is illustrated by this situation? A Nondisjunction B Codominance C Crossing over D Incomplete Dominance

The correct option is B) Codominance

Explanation:

Codominance occurs when the two alleles of a gene are neither dominant or recessive over one another. As a result, both the alleles are expressed and the phenotype shows the traits of both the alleles of the gene. In the scenario discussed in the question, both brown and white coat were seen in the coats of the rabbits because of co- dominance. Both the alleles were being expressed for the trait colour.

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.

substitution is the answer in this case
