Detailed explanation-1: -So, the correct option is (i) and (ii). Q. Choose the correct statements from the options below with regard to sexual reproduction.
Detailed explanation-2: -Sexual reproduction is the process in which two parents are involved which produce two types of gamete i.e., male and female. The gametes fuse to form the zygote during fertilization. This is a compulsory event which allows the continuation of the species.
Detailed explanation-3: -Sexual reproduction does not always require two individuals. ii Sexual reproduction generally involves gametic fusion. iii Meiosis never occurs during sexual reproduction. iv External fertilisation is a rule during sexual reproduction.
Detailed explanation-4: -Answer: Sexual reproduction requires male and female gametes produced either by the same individual or by different individuals of opposite sex. Sexual reproduction generally involves gametic fusion. Meiosis occurs during sexual reproduction in diploid organisms.
Detailed explanation-5: -Sexual reproduction always involves two gametes belonging to the same species. But these gametes need not come from two different organisms. In bisexual and hermaphrodite organisms, a single individual produces both the gametes. So, the statement is false.
