Meiosis is a process that produces gametes. Using the diagram, what do you notice about the cells produced in meiosis?

Verizon [17]

Answer:

The correct option is C) Meiosis produces 4 daughter cells each with half the number of chromosomes of the original cell.

Explanation:

There are two main processes by which cell divides:

1) Mitosis

2) Meiosis

All the cells of the body divide by the process of mitosis except the sex cells. Sex cells divide by the process of meiosis.

Meiosis can e described as a type of cell division in which four daughter cells are formed each having half the number of chromosomes as the parent cell. This is because the cell has to attain half of the maternal and half of the paternal chromosomes at the time of fertilization.

Crossing over and independent assortment are the phenomenon of meiosis which bring genetic diversity among parent and children.
