Detailed explanation-1: -In dioecious species, the sexes are separate. Generally, the male gonads ripen first in hermaphroditic animals (protandry); this tends to ensure cross-fertilization. Self-fertilization is normal, however, in many species, and some species undergo sex reversal.

Detailed explanation-2: -Animal species having different sexes, male and female, are called gonochoric, which is the opposite of hermaphrodite.

Detailed explanation-3: -dioecious, /daɪˈiːʃəs/, /daɪˈiːʃɪəs/) is a characteristic of certain species that have distinct unisexual individuals, each producing either male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction.

Detailed explanation-4: -Sexual reproduction may be divided into two main categories: hermaphroditism and dioecy (Botany)/gonochorism (Zoology). Simultaneous hermaphrodites can function in both male and female roles whereas a dioecious/gonochorist population consists of distinct male and female individuals.

Detailed explanation-5: -The unisexual animals are called dioecious animals e.g. frog, toad, cockroach etc.
