Question

Which correctly describes crossing over?

Answer 1

The correct option is A ie the process whereby non-sister chromatids exchange genetic material

• Between prophase I and metaphase I, a process known as crossing over occurs in which two homologous non-sister chromatids join up and exchange various pieces of genetic material to create two recombinant chromosome sister chromatids.
• When genetic material is switched between two chromosomes, this process is known as crossing over.
• It is in charge of causing genetic variation among members of a species.
• Only the reproductive cells known as gametes undergo this process.
• The steps involved in crossing over are as follows:

1) Synapsis.

2) Chromosome duplication

3) Crossing over.

4) Terminalizataion.
