What events can lead to offspring having a unique arrangement of their parents' genes?
A) Crossing over
B) Independent assortment
C) Both of these
D) Neither of these

Question

Quizplus · Accepted Answer

Crossing over occurs during meiosis when homologous chromosomes exchange genetic material. This results in the mixing of alleles between the two chromosomes and can produce new combinations of traits in offspring.

Independent assortment occurs when homologous pairs of chromosomes separate randomly during meiosis. This means that the combination of alleles for any given trait can be mixed in a variety of ways, leading to unique arrangements of genes in offspring.

Together, these two processes contribute to the genetic diversity of offspring by producing new combinations of alleles that are different from those present in their parents.
