Question

question 9
if a cell nucleus contains 20 chromosomes at the end of telophase i, how many chromosomes will a single gamete contain at the end of telophase ii?
20
10
23
40
2

Explanation:

Meiosis is a type of cell division that results in the formation of gametes. In meiosis I (telophase I), the chromosome number is reduced by half. Then in meiosis II (telophase II), the sister chromatids separate, but the chromosome number per cell does not change from the end of telophase I to the end of telophase II for each resulting gamete. If there are 20 chromosomes at the end of telophase I, each gamete at the end of telophase II will have the same number of chromosomes as at the end of telophase I for that cell line (since meiosis II is similar to mitosis in terms of chromosome - sister chromatid separation without further reduction in chromosome number per cell).

Answer:
