Question

The diagram shows the process of meiosis. How many divisions are required to decrease chromosome numbers and produce gametes?

A) 1
B) 2
C) 3
D) 4

Answer 1

2 is the correct answer

2 divisions are required to decrease chromosome numbers and

produce gametes

Answer 2

The right answer is 2 divisions.

Meiosis follows the replication of DNA from a reproductive cell (male or female). It allows the passage of a so-called diploid mother cell to 2n chromosome homologous chromosomes to 4 single-chromosome haploid daughter cells. For that it must pass by two successive divisions, the first division is reductionelle generating two diploid cells with n chromosomes. the second division is equational giving 4 haploid cells to n chromosomes from the two preceding cells.
