Monoecious organisms | Dioecious organisms |
Monoecious means that both the male and female reproductive organs are present in the same organisms or plants. | Dioecious means that the male and female reproductive organs are distinct, that is, they are present in two separate organisms or plants. |
During isolation, reproduction is easy as both the reproductive organs are present in same species. | Reproduction is not possible in isolation. Both the sexes need to be present. |
Inbreeding depression is caused due to which the variability is decreased. | Heterozygosity and genetic variabilty is increased due to exchange of gametes. |
e.g. earthworms, corns, oak tree etc. | e.g. human beings, dogs, chickens, asparagus etc. |
