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.

To know more about crossing over, refer to the following link:

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.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
