New combinations of linked genes are due to which of the following?
A)Nondisjunction
B)Crossing over
C)Independent assortment
D)Mixing of sperm and egg
E)Deletions

Question

Quizplus · Accepted Answer

New combinations of linked genes are due to crossing over, where homologous chromosomes exchange genetic material during meiosis. Nondisjunction can lead to aneuploidy (abnormal chromosome number), independent assortment can lead to new combinations of non-linked genes, mixing of sperm and egg can lead to genetic variation, and deletions can result in loss of genetic material but may not necessarily lead to new combinations of linked genes.
