Question

cell having 24 chromosomes undergoes mitotic division. What will be the chromosome

number (N) of the cell during its metaphase and chromosomal number in daughter cells?

Explain it with reason?​

Answer 1

Answer:

12 chromosomes each

Explanation:

If a cell has 24 chromosomes before cell division then daughter cell resulting from mitotic division will have 24 chromosomes while daughter cell resulting from the meiotic division will contain 12 chromosomes each

Answer 2

Answer:

From a diploid germ cell 2n =24 double stranded chromosomes, meiosis will produce four gamete haploid cells n =12 single stranded chromosomes.

Meiosis produces four with half because double stranded chromosomes represents DNA replication. Twice as much DNA as a diploid cell needs.

From a diploid germ cell 2n =24 double stranded chromosomes, mitosis will produce two diploid daughter cells 2n =24 single stranded chromosomes for the same reason.

DNA replication doubles the genome before cell division. Sister chromatids of double stranded chromosomes represent the replicated DNA. During cell division, sister chromatids of double stranded chromosomes are separated into different cells.

Meiosis has two stages, the first separating homologous pairs of double stranded chromosomes, and then the second stage separating sister chromatids into four haploid (n) gametes.
