The male produces relatively smaller gamete called the ‘sperms’, while the female produces relatively larger gametes called the ‘ovum’, thereby exhibiting anisogamy (where there is a fusion of two dissimilar gametes). This takes place so as to increase the chances of male gamete meeting the female gamete.
Why are male gametes smaller than female?
It is an advantage to produce lots of gametes rather than a few. But production is costly, and could result in cutting down the size of individual gametes: males produce a lot of sperm, but each one is very small. In other words, the number of gametes produced is inversely proportional to gamete size.
Do males or females have larger gametes?
Female gametes are larger than male gametes. This is not an empirical observation, but a definition: in a system with two markedly different gamete sizes, we define females to be the sex that produces the larger gametes and vice-versa for males (Parker et al.
Do females produce larger gametes?
Systems in which the two sexes (males and females) are separate, i.e. male individuals produce small gametes and female individuals produce large gametes.
What is the female sperm called?
Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm.
Why do only male gametes have tail?
Male gametes or sperms are motile. The tail helps the sperm to swim through the reproductive tract of the female to reach the oviduct.
