Which diagram demonstrates how crossing-over contributes to genetic variety during meiosis?

a) answer choice a

b) answer choice b

c) answer choice c

d) answer choice d

Crossing over is defined as the exchange of genetic material during the formation of germ cells. The given image out of which crossing over is best described is:

C) Option C- Answer choice C

Crossing over is the process of swapping of genetic material occurring during the formation of reproductive cells. Crossing-over is an essential process that causes unique combinations and variation in the daughter cells. The process occurs between prophase I and metaphase I.

Reasons for incorrect answers:

Therefore, the crossing over occurs during meiotic division in which exchange of genetic material takes place.

Crossing a different strand of chromosomes is called crossing over.

Crossing over helps in the following ways:-

Hence, according to the question in option B the chromosomes are changing the genes.

Therefore, option B is correct.
