Can anyone please tell me the definition of Meiosis?
Meiosis is a specialised type of cell division which brings down chromosome number of parent cell to half in four daughter cells. Meiosis involves two successive cell divisions.
Meiosis may take place in plants, animals, or fungi. Generally in plants and animals, haploid gametes are generated by meiosis. Gametes fuse to form zygote and diploid chromosome number is again established for the new progeny.
In some lower plants, meiosis takes place in zygote so that haploid spores are formed. Such spores multiply by mitosis to form haploid plant bodies.
