Question

Which one the following is a requirement for sexual reproduction?

• A. Male and female parents
• B. Production of gametes
• C. Optimal environmental conditions
• D. Aquatic habitat

Answer 1

Answer: (B)

Production of gametes

Sexual reproduction is the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by the other (female). Nearly all animals employ a diploid-dominant life-cycle strategy in which the only haploid cells produced by the organism are the gametes. Early in the development of the embryo, specialized diploid cells, called germ cells, are produced within the gonads (such as the testes and ovaries)

So, the correct answer is 'production of gametes'
