Why is meiosis important in sexual reproduction?
A
It produces genetically identical cells.
B
It increases the number of chromosomes in gametes.
C
It reduces the chromosome number by half, creating haploid gametes.
D
It occurs only in somatic cells.
검증된 단계별 안내1
Understand that meiosis is a type of cell division that reduces the chromosome number by half, which is crucial for sexual reproduction.
Recognize that meiosis results in the production of haploid gametes (sperm and egg cells), each containing half the number of chromosomes of the parent cell.
Realize that when two haploid gametes fuse during fertilization, they form a diploid zygote with a complete set of chromosomes, restoring the original chromosome number.
Acknowledge that meiosis introduces genetic diversity through processes like crossing over and independent assortment, which are essential for evolution and adaptation.
Note that meiosis does not occur in somatic cells; it is specific to germ cells involved in reproduction.
