Question

Quizplus · Accepted Answer

Organisms with an odd number of chromosome sets are usually sterile because their gametes often end up with an unbalanced set of chromosomes. This imbalance occurs because chromosomes cannot pair up and segregate evenly during meiosis, leading to gametes that are not viable or capable of successful fertilization.
