Question

a single cell with seven pairs of homologous chromosomes goes through meiosis i. how many cells result at the end of meiosis i? how many chromosomes exist in each cell? are the chromosomes in each cell made of sister chromatids?

Explanation:

Meiosis I is the first division of meiosis, which separates homologous chromosome pairs. A single diploid cell entering meiosis I divides once to produce two haploid daughter cells. The original cell has 7 pairs (14 total) homologous chromosomes; after meiosis I, each daughter cell gets one chromosome from each pair, so 7 chromosomes per cell. Sister chromatids remain attached at the centromere until meiosis II, so chromosomes in meiosis I products still consist of sister chromatids.

Answer:

1. 2 cells result at the end of meiosis I.
2. Each cell contains 7 chromosomes.
3. Yes, the chromosomes in each cell are made of sister chromatids.
