Which cell is formed as a result of meiosis?<br> O bone<br> O egg<br> O muscle<br> Oskin
Andrews [41]

The egg is formed as a result of meiosis.

Meiosis is cell division that forms haploid cells (cells with half the amount of chromosomes as diploid cells).

Haploid cells in humans are sperm (male) and egg (female)

The other cells, like the skin, bone and muscle are a result of mitosis -which is different from meiosis.
