How are haploid cells formed
WebBoth the secondary oocyte and polar body are haploid cells. The secondary oocyte has most of the cytoplasm from the original cell and is much larger than the polar body. … WebFertilization is the process in which haploid gametes fuse to form a diploid cell called a zygote. To ensure that each zygote has the correct number of chromosomes, only one sperm can fuse with one egg. Stages of human development. Zygotic stage: The zygote is formed when the male gamete (sperm) and female gamete (egg) fuse.

WebThere are two ways cell division can happen in humans and most other animals, called mitosis and meiosis. When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides by way of meiosis, it produces four cells, called gametes. Gametes are more commonly called sperm in ...
