During meiosis I, _____________________. Group of answer choices homologous chromosome pairs are separated the chromosome number
spayn [35]

Homologous chromosome pairs are separated

Meiosis 1 refers to the initial stage of meiosis where one parent cell divides into two daughter cells. This stage is where homologous pairs of chromosomes will segregate and separate from each other and move into the two daughter cells which result in the division of the total chromosomal number by half.

<h3>What happens during Meiosis 1 ?</h3>

Meiosis I ends when the chromosomes of each homologous pair arrive at opposing poles of the cell.

  • The microtubules disintegrate, and a new nuclear membrane forms around each haploid set of chromosomes.

  • The chromosomes uncoil, forming chromatin again, and cytokinesis occurs, forming two non-identical daughter cells.

What statement best explains why meiosis produces haploid cell rather than diploid cells
Shkiper50 [21]

The right answer is Haploid cells join to form an organism that has a complete set of chromosomes.

Meiosis makes it possible to pass from a cell to 2n chromosomes to 4 cells with n chromosomes, thus ensuring the passage from the diploid phase to the haploid phase.

So from the  fertilization phase to the meiosis phase, the cells will be diploid (2n chromosomes). From the meiosis phase to the fertilization phase, it is the haploid phase (n chromosome).
