Question

Put the following steps in order for meiosis and the preceding interphase in a female. Hint: For each step, determine whether it is in G1, S G2, Prophase 1, Prophase 2, Metaphase 1, Metaphase, 2, Anaphase 1, Anaphase 2, Telophase 1, Telophase 2, after the first cytokinesis or after the second cytokinesis. Question 2 options: Sister chromatids are created here 2 X chromosome sisters move in opposite directions on the spindle An X chromosome appears in which the 2 sisters have different alleles A cell exists with one X chromosome that has 2 attached sisters The 2 X chromosomes pair

Answer 1

Question 1. The steps occur in the following order:

INTERPHASE

1. G1

2. S

3. G2

MEIOSIS I

4. Prophase 1

5. Metaphase 1

6. Anaphase 1

7. Telophase 1

8. First Cytokinesis

MEIOSIS II

9. Prophase 2

10. Metaphase 2

11. Anaphase 2

12. Telophase 2

13. Second cytokinesis

Question 2

Sister chromatids are created here (interphase)

The 2 X chromosomes pair (prophase 1)

A cell exists with one X chromosome that has 2 attached sisters (prophase 1)

An X chromosome appears in which the 2 sisters have different alleles (prophase 1)

2 X chromosome sisters move in opposite directions on the spindle (anaphase1)

Step-by-step explanation:

During interphase the cell prepares to divide. During meiosis 1 Homologous chromosomes are segregated and the ploidia is reduced from diploid to haploid in a reductive division where the sister chromatids are held together. Unlike meiosis I, meiosis II is an "equational" division analogous to mitosis where sister chromatids are secreted creating four haploid cells.
