Question

a cell has completed meiosis i and the first cytokinesis, and is just beginning meiosis ii. which of the following statements describes its genetic contents? a) it has half the amount of dna as the cell that began meiosis. b) it has twice the dna of the cell that began meiosis. c) it has one-fourth the dna and one-half the chromosomes as the cell that began meiosis. d) it is genetically identical to the other cells produced by this cytokinesis.

Answer 1

A cell at the beginning of Meiosis II contains a haploid set of chromosomes with half the amount of DNA as the original diploid cell that entered Meiosis I.

Therefore, the correct answer is: option a) it has half the amount of dna as the cell that began meiosis.

Step-by-step explanation:

When a cell has completed Meiosis I and the first cytokinesis, and is just beginning Meiosis II, it has half the amount of DNA as the cell that began meiosis.

This is because Meiosis I included the reduction division where homologous chromosomes were segregated into two new cells.

As it enters Meiosis II, no DNA replication occurs between the two divisions; therefore, each daughter cell contains one complete set of chromosomes, which is haploid.

In Meiosis II, sister chromatids will separate but the overall chromosome count remains the same. In human cells, this means it has 23 chromosomes, one from each original homologous pair.
