Question

Crossing over prevents homologous chromosomes from separating during meiosis i. true or false?

Answer 1

Crossing over does not prevent homologous chromosomes from separating during meiosis, hence, the statement is false.

CROSSING OVER:

• Crossing over is the process whereby non-sister chromatids of homologous chromosomes exchange their genetic materials.

• Crossing over occurs specifically during the prophase I stage of meiosis I. Via this process, genetic diversity is likely to occur in the daughter cells.

• Crossing over only assures that genes of homologous chromosomes are recombined, it does not stop them from separating in the Anaphase stage.

• Therefore, crossing over does not prevent homologous chromosomes from separating during meiosis, hence, the statement is false.
