The outbreeding device where anthers and stigmas mature at different times is called as -------------.
Options
- AUnisexuality
- BDichogamy
- CHerkogamy
- DHeteromorphy
Correct answer
B. Dichogamy
Step-by-step solution
Dichogamy is an outbreeding device in which the anthers and stigmas of a bisexual flower mature at different times to prevent self-pollination.
It is of two types: protandry, where anthers mature earlier than the stigma, and protogyny, where the stigma matures earlier than the anthers.
Unisexuality refers to the presence of only one type of reproductive organ in a flower.
Herkogamy refers to the presence of a physical barrier between the anther and stigma.
Heteromorphy refers to the presence of different forms of flowers, such as varying lengths of styles and stamens.
