Verified step by step guidance1
Understand that meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically distinct daughter cells.
Recognize that a parent cell with 46 chromosomes is diploid, meaning it has two sets of chromosomes (2n).
During meiosis, the cell undergoes two rounds of division: meiosis I and meiosis II.
In meiosis I, homologous chromosomes are separated, reducing the chromosome number by half. This means each daughter cell will have one set of chromosomes (n).
Since the parent cell starts with 46 chromosomes, each daughter cell will have 23 chromosomes after meiosis, which is half of the original number.
