A
The starting cell has twice the number of chromosomes as each gamete.
B
The starting cell and each gamete have the same number of chromosomes.

검증된 단계별 안내1
Understand that meiosis is a type of cell division that reduces the chromosome number by half to produce gametes (sperm or egg cells).
Recall that the starting cell in meiosis is a diploid cell, meaning it contains two sets of chromosomes, one from each parent. This is often represented as \$2n$.
Recognize that the gametes produced by meiosis are haploid cells, containing only one set of chromosomes, represented as \(n\).
Compare the chromosome number of the starting diploid cell (\$2n\() to that of the resulting haploid gametes (\)n$).
Conclude that the starting cell has twice the number of chromosomes as each gamete because \$2n\( is double \)n$.
