If a diploid organism has a genome consisting of 22 chromosomes, its gametes will have ___ chromosomes

• 20

Which of the following types of cells in humans are considered diploid?

• egg cell
• somatic
• sperm cell
• gamete

The correct number of chromosomes is maintained during fertilization in sexual reproduction by-

• meiosis, which reduces the chromosome number of the gamete by one half
• chromosomes being copied immediately after fertilization of the gametes
• mitosis, which maintains the number of chromosomes in the daughter cells
• half of the chromosomes being destroyed immediately after fertilization of the gametes.
