Question

which of the following choices are true and which are false about the pictured cell?
true
drag appropriate answer(s) here
in metaphase ii
10 homologous pairs of chromosomes
n = 5
10 sister chromatids
diploid number of 10
20 sister chromatids
5 homologous pairs of chromosomes
in metaphase i
2n = 20

Explanation:

In the picture, homologous chromosomes are paired up at the equator, which is characteristic of metaphase I. There are 5 homologous pairs of chromosomes. Each chromosome has 2 sister - chromatids, so there are 20 sister chromatids in total. The diploid number ($2n$) is 10 and the haploid number ($n$) is 5. Metaphase II would have non - paired chromosomes.

Answer:

True: in metaphase I, 20 sister chromatids, 5 homologous pairs of chromosomes, $n = 5$, diploid number of 10
False: in metaphase II, 10 homologous pairs of chromosomes, 10 sister chromatids, $2n=20$
