Detailed explanation-1: -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. Overview of the process of sexual reproduction.

Detailed explanation-2: -Through the union of sperm and egg, mammals reproduce sexually. Males, once mature, produce viable sperm that can fertilize the egg (oocyte), released by mature females during a process called ovulation. The fertilized egg can develop into offspring.

Detailed explanation-3: -Sexual Reproduction in Animals. The process in which the male and female gametes fuse together to form a new individual is called sexual reproduction.

Detailed explanation-4: -Two major types of sexual reproduction are syngamy and conjugation. Syngamy refers to the fusion of haploid sex cells resulting in the formation of a diploid zygote. Thus, in essence, syngamy refers to fertilization.

Detailed explanation-5: -Asexual reproduction in animals occurs through fission, budding, fragmentation, and parthenogenesis. Sexual reproduction may involve fertilization inside the body or in the external environment.
