Question

1) a. Meiosis is the process in which a parent cell divides to produce: Select one: a. 4 cells that are genetically identical to the parent. b. 2 daughter cells that differ genetically from the parent. c. 2 cells that are genetically identical to the parent. d. 4 daughter cells that differ genetically from the parent. Clear my choice.

b) This cell is in Anaphase I of meiosis. How many chromosomes and chromatids will be in the resulting daughter cells at the end of meiosis II?

Select one:

a. 3 chromosomes, 3 chromatids

b. 6 chromosomes, 12 chromatids

c. 3 chromosomes, 6 chromatids

d. 6 chromosomes, 6 chromatids

e. It depends on whether crossing over occurred or not.

Answer 1

Answer -1 (a)

In this question option d ( 4 daughter cells that differ genenitically from parent will be correct .

In the meiosis two stages occurs meiosis first and meiosis second ,in the meiosis first homologous chromosome are separate and number of chromosome is half a,nd meiosis second centromere break same as mitosis.

Representation is given blow __



Answer -(b)

In this question option b and c can be correct because numbers of chromosome and chromatids only depends on numbers of parental chromosome in a parental cell. Because in the meiosis parental cell divide in to four haploid cells .In which each pair have single chromosome and two chromatids. So we can determine the number of chromosome and chromatids only on the basis of number of chromosome present in parental cell.
