NEET BIOLOGY

Detailed explanation-1: -So, each sperm contains 50% of the father’s genes and each egg contains 50% of the mother’s genes. This makes gametes different from other cells in the body. A basic human body cell contains 46 chromosomes, but the egg and sperm only contain half that number, or 23 chromosomes.

Detailed explanation-2: -To form a fetus, an egg from the mother and sperm from the father come together. The egg and sperm each have one half of a set of chromosomes. The egg and sperm together give the baby the full set of chromosomes. So, half the baby’s DNA comes from the mother and half comes from the father.

Detailed explanation-3: -Asexual Reproduction: One parent always passes on a duplicate of all of its genes to offspring. Rare mutations aside, offspring can only be genetically identical copies, or clones, of the parent.

Detailed explanation-4: -When a male gamete and a female gamete are involved in reproduction, this method is referred to as sexual reproduction. Here the male and female gametes fuse during fertilization to produce a single-celled zygote. The zygote subsequently develops into an embryo which further develops into a new individual.

Detailed explanation-5: -Sexual Reproduction: The type of reproduction beginning from the fusion of male and female gametes is known as sexual reproduction. In this process of sexual reproduction, a male and a female gamete (reproductive cells) fuse to form a single cell called Zygote.
