คำอธิบาย
Somatic cells are diploid, meaning they have two sets of chromosomes, one from the mother and one from the father. During mitosis, somatic cells replicate their DNA and divide to produce two daughter cells that each receive a complete copy of the genome.
If a somatic cell has 8 chromosomes, then the gamete will have 4 chromosomes. This is because gametes have half the number of chromosomes as somatic cells.
