How can we compare gametes ova and sperm
WebGametes are reproductive cells that unite during sexual reproduction to form a new cell called a zygote. This condition is called ‘anisogamy’ or ‘heterogamy’, wherein the female and male gametes are of different sizes (in the case of humans, the ovum is ~20 times larger than the sperm cell). ‘Isogamy’, in contrast, is the state of ... WebGametogenesis is a biological process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid gametes.Depending on the biological life cycle of the organism, gametogenesis occurs by meiotic division of diploid gametocytes into various gametes, or by mitosis. For example, plants produce gametes through …

To form identical or monozygotic twins, one fertilised egg (ovum) splits and develops into two babies with exactly the same genetic information. To form fraternal or dizygotic twins, two eggs (ova) are fertilised by two sperm and produce two genetically unique children.
