NEET BIOLOGY

Detailed explanation-1: -In sexual reproduction, genetic information from two parent cells are passed on to an offspring. Female organisms and male organisms make specialized cells called gametes. Gametes from female parents are called eggs. Gametes from male parents are called sperm.

Detailed explanation-2: -During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.

Detailed explanation-3: -The process of union of male and female gametes is called fertilisation. Male and female gametes are a product of meiosis. Reduction division is the first division of meiosis in which the number of chromosomes is reduced to half the original number.

Detailed explanation-4: -Through the process of fertilization, egg and sperm join to make a cell with 46 chromosomes (23 pairs), called a zygote.
