In sexually reproducing organisms, what is the primary purpose of meiosis?
A
To replicate DNA without cell division so the cell can increase its size
B
To produce genetically identical diploid daughter cells for growth and tissue repair
C
To produce haploid gametes and generate genetic variation through recombination and independent assortment
D
To create two diploid cells that each contain one complete set of homologous chromosomes
검증된 단계별 안내1
Understand that meiosis is a specialized type of cell division occurring in sexually reproducing organisms.
Recognize that the main goal of meiosis is to reduce the chromosome number by half, producing haploid cells from diploid cells.
Identify that these haploid cells are gametes (sperm and egg), which are necessary for sexual reproduction.
Note that meiosis introduces genetic variation through two key processes: recombination (crossing over) and independent assortment of chromosomes.
Conclude that the primary purpose of meiosis is to produce haploid gametes and generate genetic diversity, which is essential for evolution and adaptation.
