In Meiosis I, cytokinesis usually occurs after telophase I and produces:
A
Four diploid cells.
B
Two haploid cells.
C
Four haploid cells.
D
Two diploid cells.
Verified step by step guidance1
Understand that meiosis is a type of cell division that reduces the chromosome number by half, resulting in the production of haploid cells from a diploid cell.
Recall that meiosis consists of two stages: Meiosis I and Meiosis II. Meiosis I is the reductional division where homologous chromosomes are separated.
During Meiosis I, the process includes several phases: prophase I, metaphase I, anaphase I, and telophase I, followed by cytokinesis.
In telophase I, the homologous chromosomes reach opposite poles of the cell, and the cell begins to divide. Cytokinesis follows, splitting the cytoplasm and forming two separate cells.
Each of the two cells produced after cytokinesis in Meiosis I is haploid, meaning they contain half the number of chromosomes compared to the original diploid cell. Therefore, the correct answer is 'Two haploid cells.'
