उत्तर
Sexual reproduction involves the fusion of two types of gametes i.e., the male and the female gametes. The zygote formed contains a fusion of both the sperm nucleus and the egg nucleus. Due to this, the new individual has characteristics which are similar to both the parents while some characteristics which are different from both the parents. Thus, the new individual formed from sexual reproduction inherits the characteristics of both the parents. For example, if the father has black hair while the mother has brown hair, the chances are that their offspring may have either black or brown hair.
