Marysya12 [62]

Answer:

A diploid cell has 28 chromosomes. When meiosis occurs, how many chromosomes are there during Prophase I?
murzikaleks [220]

Answer:

The correct answer will be option-B

Explanation:

Meiosis is a way of cell division used by the organism to produce a large number of cells from a few parent cells. This is used to make the gametes of the body.

Meiosis produces four daughter cells from a single parent cell in two stages that is meiosis I and II. Each stage proceeds in four phases- prophase, metaphase, anaphase and telophase.

The reduction division of the chromosomes or the ploidy number takes place during anaphase I of meiosis I and not prophase I which is the initial phase of the division. Therefore, during prophase I the chromosome number of the cell remains the same.

Thus, Option-B is the correct answer.
