प्रश्न
Name two main processes of sexual reproduction
उत्तर
Two main processes of sexual reproduction:
(1) Meiosis: It is a process of cell division in which the chromosome number is reduced to half to form haploid gametes (2n→n).
(2) Fertilisation: The union of the haploid male gamete with the haploid female gamete to form the diploid zygote is called fertilisation. By fertilisation, the chromosome number again becomes diploid (2n).
