Question
Select the correct statement.
- Egg and sperm come from two separate organisms of the same species.
- Egg and sperm come from two same organisms of different species.
- Egg and sperm come from the male organism.
- Egg and sperm come from the female organism.
Hint:
Egg and sperms are female and male gametes, respectively.
The correct answer is: Egg and sperm come from two separate organisms of the same species.
- Sexual reproduction involves two individuals (male and female) of the same species
- The reproduction involves fusion of a male and female gamete
- The male gamete is called sperm
- The female gamete is called egg or ova
- The fusion of a male and female gamete is called fertilization
