Question

Which of the following correctly explains the steps pictured below?

a Prophase II, Metaphase II, Anaphase II
b Prophase II, Anaphase II, Telophase II
c Prophase I, Prophase II, Metaphase I
d Prophase I, Metaphase I, Anaphase I

Answer 1

Its kinda hard to tell but it looks like A because you can see the chromosome appears to be dividing at the centromere in the bottom illustration which is Anaphase II

Answer 2

Answer:

The answer is :

a) Prophase II, Metaphase II, Anaphase II

Explanation:

The images of this question describe Meiosis II as it can be seen single chromosomes not homologous pairs of them.

Prophase II, Metaphase II and Anaphase II form part of meiosis II. In meiosis II the chromosomes that were duplicated in Meiosis I, split to form two haploid gametes. Then during the fertilization those gametes come together to form a new diploid cell.

In Prophase II there is no duplication, just the replication of centrioles happens. So the daughter centriole is formed and placed perpendicular to its mother. Then the nuclear envelope breaks down and next to the spindle form in Meiosis I a new plane is created.

In Metaphase II odd chromosomes are align in the metaphase plate (in the middle of the spindle).

Finally, in Anaphase II, the centromeres split, and the chromatids move to the opposite pole of the spindle.
