Question

Quizplus · Accepted Answer

Crossing-over is a process that occurs during meiosis where homologous chromosomes exchange alleles, resulting in genetic diversity in offspring. It is not considered a chromosomal mutation or gene mutation, as it does not result in a change in the number or structure of chromosomes or a change in the sequence of DNA. It can occur on any chromosome, not just the X chromosome.
