17

Following meiosis, the daughter cells are genetically identical to the parent cell.

Meiosis results in two daughter cells with the haploid (n) number of chromosomes.
A)True
B)False
19

Meiosis II proceeds through its four phases just like mitosis.
A)True
B)False
20

The random line-up of homologues at the equator in metaphase I of meiosis I ensures the production of different gametes each time it occurs.
A)True
B)False
