Question

6. (2 pts). Assume that a cell about to undergo cell division has a diploid number of 8. a. How many homologous pairs of chromosomes are present in the nucleus of this cell? d. Is the cell in meiosis I considered haploid or diploid? e. How many chromatids would be present during prophase 1? f. How many chromosomes are present in metaphase I of meiosis? g. How many chromatids would be present in one cell at the end of meiosis 1? h. How many chromosomes would be present in one cell at the end of meiosis I1?

Explanation / Answer

6) The diploid number of the cell is 8.

A) Eight chromosomes can be arranged in 4 homologous pairs.

B) At the end if meiosis I division, haploid number of chromosomes are formed. Considering the diploid number of chromosomes, we can say that the cell is presently in meiosis I stage.

C) The number of chromatids during prophase I stage is 16.

D) The number of chromosomes in metaphase I is 8.

E) At the end of meiosis, the number of chromatids in each cell would be 8.

F) The number of chromosomes in each cell at the end of meiosis 2 is 4.
