In sexually reproducing organisms, what is the primary result of meiosis?
A
Four genetically identical diploid daughter cells are produced from one diploid cell.
B
One diploid cell is produced by fusion of two haploid cells.
C
Four genetically distinct haploid cells (gametes) are produced from one diploid cell.
D
Two genetically identical diploid daughter cells are produced from one diploid cell.
검증된 단계별 안내1
Understand that meiosis is a type of cell division specific to sexually reproducing organisms, which reduces the chromosome number by half to produce gametes.
Recall that the starting cell in meiosis is diploid (2n), meaning it contains two sets of chromosomes, one from each parent.
Recognize that meiosis consists of two consecutive divisions: meiosis I and meiosis II, which together result in four daughter cells.
Note that during meiosis, genetic recombination (crossing over) and independent assortment occur, leading to genetic variation among the daughter cells.
Conclude that the final product of meiosis is four genetically distinct haploid (n) cells, each containing one set of chromosomes, which are the gametes.
