One of the following is not a method of asexual reproduction:
Correct answer: B. Gametogenesis
- A. Sporulation
- B. Gametogenesis
- C. Apomixis
- D. Parthenogenesis
Explanation
Gametogenesis is not a type of asexual reproduction. Gametogenesis is the process by which haploid gametes (sex cells) are produced within the gonads (testes in males and ovaries in females) of sexually reproducing organisms. This process involves specialized cell divisions, such as meiosis, which reduce the chromosome number by half, resulting in gametes that contain only one set of chromosomes (haploid). Asexual reproduction, on the other hand, involves the production of offspring that are genetically identical to the parent organism and does not involve the fusion of gametes.

About Reproduction
Human reproduction covers the male and female reproductive organs, gamete formation, fertilization, implantation and hormonal regulation. The menstrual cycle includes ovarian and uterine changes controlled by pituitary and ovarian hormones, while sexually transmitted diseases are studied through their causes, transmission, symptoms, prevention and effects on fertility.
