During which stage of sex cell formation does the number of chromosomes decrease from diploid (2n) to haploid (n)? a. prophase 1 b. prophase 2 c anaphase 1 d. anaphase 2

c. anaphase 1

Explanation:

Sex cells are formed during meiosis, which is the process in which the mother cell forms four daughter cells with half the chromosomal number. Meiosis occurs in two successive divisions: meiosis I (reductive) and meiosis II (equational).

During meiosis I, a phase called anaphase 1 occurs, in which phase the homologous chromosomes are separated. For this reason meiosis I is called reductive, since the cell that was 2n, with the pairs of homologues, turns into two n cells, with only one chromosome in each pair.

the correct answer is b. possesses the characteristic of compartmentalization of organelles, wherein the organelles are bound by membranes.
