Use the diagram below to help you to choose ALLL the CORRECT answers for the question: What are the differences between Meiosis i and Meiosis II? (MULTIPLE CHOICE)

A In Metaphase I and Metaphase II the chromosomes line up differently because there are a different number of copies

B Telophase and cytokinesis do NOT happen in Meiosis II

C After Meiosis II the 4 daughter cells undergo cell specialization to become eggs or sperm, which does not happen after Meiosis I

D In Prophase I the chromosomes crossover, in Prophase II they do not crossover

D In Prophase I the chromosomes crossover, in Prophase II they do not crossover

Explanation:

Meiosis is a type of cell division in which four daughter cells, which are genetically different from one another, are produced. The daughter cells have their chromosomal number reduced by half. Since, the meiotic process aims at producing haploid gametes, it occurs in a series of two-division steps viz: meiosis I and meiosis II.

Meiosis I involves the separation of homologous chromosomes into two daughter cells while the meiosis II involves separation of chromatids to make four daughter cells. One major difference between meiosis I and meiosis II is that in the PROPHASE of meiosis I, a unique process called CROSSING OVER occurs but does not occur in meiosis II (as seen in the attached image).

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
