NEET BIOLOGY

Detailed explanation-1: -A spermatozoon provides half of the nuclear genetic material to the diploid offspring via fertilization.

Detailed explanation-2: -The amount of DNA per spermatozoon of the 21 fertile males is very constant and uniform within each individual and among the 21 different individuals. The mean amount of DNA in arbitrary units is 1.22±0.005 per sperm and is approximately one-half that of human somatic cells which is 2.66±0.05. 2.

Detailed explanation-3: -The sperm and egg are specialised cells called gametes and are unique in comparison to most of the other cells in the body, as they only contain half the usual number of chromosomes. At fertilisation, half of your father’s genome is mixed with half of your mother’s genome to form your complete genome.

Detailed explanation-4: -The sperm cells have only 23 chromosomes, or half of the usual number. When a sperm cell unites with the ovum, which also has 23 chromosomes, the resulting 46 chromosomes determine the offspring’s characteristics.

Detailed explanation-5: -These sex cells are also called reproductive cells or gametes. Sperm cells are produced in men’s testicles and egg cells are produced in women’s ovaries. Sex cells are different from other cells in one special way: Put simply, they only have one half of the total amount of human genetic information.
