chromosomes are there in the following types of mouse cells?

1. Daughter muscle cell formed from mitosis
2. Egg cell
3. Fertilized egg cell

 

Q2. A nuclear envelope forms around each set of chromosomes and cytokinesis occurs, producing four daughter cells, each with a haploid set of chromosomes.

2. metaphase I
3. anaphase I
4. telophase I
5. prophase II
6. metaphase II
7. anaphase II
8. telophase II
9. cytokinesis
