Fertilization

Explanation

1 Fertilization forms the zygote which eventually produces new offspring
2 Fertilazation restores diploid number of chromosomes in the zygote as two haploid gametes come together in a zygote
3 During fertilization centrioles are passed on to the ovum due to this secondary occyte can complete meiosis II The fertilization thus concludes the process of oogeniesis
4 By fretilization the gentic characters of two parents are mixed this leads to variation and has significance in evolution
5 Due to fetilization the sex young one is determined
