NEET BIOLOGY

Detailed explanation-1: -Each parent contributes a gamete-a sex cell that has half of the normal DNA of a regular body cell. In males, the gametes are sperm and in females, the gametes are eggs. When these two gamete combine during fertilization, the result is a zygote, which then continues to develop into an embryo.

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

Detailed explanation-3: -Sexual reproduction occurs when the sperm from the male parent fertilizes an egg from the female parent, producing an offspring that is genetically different from both parents.

Detailed explanation-4: -Fertilization: A Sperm and an Egg Form a Zygote When a sperm cell penetrates and fertilizes an egg, that genetic information combines.

Detailed explanation-5: -In a process called fertilisation, the two gametes join and their chromosomes combine, so that the fertilised cell contains a normal complement of chromosomes, with some from each parent flower.
