Question

evaluate whether the following statement is true or false:
what happens in the middle phase of meiosis i is identical to what happens in the middle phase (metaphase) of mitosis.
true
false
evaluate whether the following statement is true or false:
the events that happen in meiosis i explain why meiosis is a reduction division. at the start of meiosis i, the cell is diploid: it has two of each chromosome type and homologous pairs present. at the end, each daughter cell is haploid (only one of each type present).
true
false

Explanation:

• First statement:
• In metaphase of mitosis, individual chromosomes (each with two sister chromatids) align at the equatorial plate. In metaphase I of meiosis, homologous chromosome pairs (bivalents) align at the equatorial plate. So, they are not identical.
• Second statement:
• Meiosis I is a reduction division. It starts with a diploid cell (with homologous chromosome pairs). Homologous chromosomes separate during anaphase I, and at the end of meiosis I, the daughter cells are haploid (with half - the chromosome number as the parent cell).

Answer:

• First statement: B. False
• Second statement: A. True
