An inversion in a human chromosome often results in no demonstrable phenotypic effect in the individual. What else may occur?
A) There may be deletions later in life.
B) Some abnormal gametes may be formed.
C) There is an increased frequency of mutation.
D) All inverted chromosomes are deleted.
E) The individual is more likely to get cancer.

Question

Quizplus · Accepted Answer

Inversions can result in abnormal gametes due to the potential misalignment and crossing over during meiosis. This can result in offspring with genetic disorders or reduced fertility.

Answer: A
 Although an inversion may not have an immediate phenotypic effect, it could disrupt a gene or regulatory sequence, potentially leading to deletions or other mutations later in life.

Answer: C, D, E
 None of these choices are accurate. There is no evidence to suggest that inversions increase the frequency of mutation or result in all inverted chromosomes being deleted. In addition, while some genetic abnormalities can increase the risk of cancer, there is no direct link between inversions and cancer.
