which of the following accurately explains why human siblings differ in appearance from one another?

A). each of them inherits a unique member of chromosomes.
B). gametes have higher rates for mutations, which allow for more genetic diversity.
C). alleles are interchanged during meiosis, which results in genetically distinct offspring.
D). genes are rearranged during mitosis, which results in new combinations of chromosomes.

B) That's not true. Gametes have no higher tendency for mutation, that could be dangerous: if a deletirous mutation appears, the organism could die. Mutations don't happen for a purpose, so, mutate can be extremaly bad - and usually is.

C) That's true. One of that interchangends is the crossing-over: nearby chromosomes exchanges parts. It happens in the beginning of meiosis.

D) That's not true. Mitosis is a procedement of cloning cells. If a new combination happen, then we have a mutation and the cell will be probably killed.

The siblings differ in appearance from one another as alleles get interchanged at the time of meiosis, which eventually results in genetically distinct offspring.

What is crossing over?

It is the swapping of the genetic material, which takes place in the germ line. During the meiosis, the paired chromosomes from each parent get arrange in a manner that identical sequences of DNA from the paired chromosomes cross over each other.

The phenomenon of crossing over takes place during the start of meiosis, in this the parts of the nearby chromosomes get interchanged. This interchanging of alleles during meiosis leads to the formation of genetically distinct offspring. Therefore, the siblings differ in appearance from one another.

Thus, the correct answer is option C.
