Answer:
Introduction:
Sexual reproduction is a process in which two individuals of opposite sexes, male and female, come together to produce offspring. In mammals, this process involves the fusion of sperm and egg, leading to the formation of a diploid zygote.
Fertilization:
Fertilization is the process by which the sperm and egg fuse to form a zygote. In mammals, fertilization occurs in the ampullary region of the female reproductive tract. The male inserts the sperm into the female reproductive tract, and the sperm are received by the ovary. From there, the sperm travel towards the ampullary region where they fuse with the egg.
Diploid Zygote Formation:
During fertilization, the haploid nucleus of the sperm fuses with the haploid nucleus of the ovum (egg) to form a diploid zygote. This diploid zygote contains the full complement of genetic material required for the development of an individual.
Sperm Activation:
Before fertilization can occur, the sperm must undergo a process called capacitation, which is the phenomenon of sperm activation in mammals. Capacitation involves several changes in the sperm, including the removal of certain proteins from the sperm membrane and the modification of its surface characteristics. These changes enable the sperm to be capable of penetrating and fertilizing the egg.
Options:
- Parthenogenesis: Parthenogenesis is a form of reproduction where an egg develops into an individual without fertilization. It does not involve the fusion of sperm and egg, so it is not the correct answer.
- Amphimixis: Amphimixis is another term for sexual reproduction, but it does not specifically refer to the process of sperm activation. Therefore, it is not the correct answer.
- Capacitation: Capacitation is the correct answer as it refers to the phenomenon of sperm activation in mammals. It involves the preparation of the sperm for fertilization by undergoing certain changes in its structure and function.
- Acrosomal reaction: The acrosomal reaction is a specific step that occurs during fertilization, where the acrosome (a structure on the head of the sperm) releases enzymes that help the sperm penetrate the egg's protective layers. While this is an important step in fertilization, it does not describe the overall process of sperm activation, so it is not the correct answer.
Therefore, the correct answer is option 'C' - Capacitation.

Therefore, the correct answer is option 'C' - Capacitation.
