Question

Continuous self pollination results in inbreeding depression. Among the following which one DOES NOT favors self pollination and encourages cross pollination?

• A. Self incompatibility
• B. Production of bisexual flowers
• C. Non- synchronous pollen release and stigma receptivity
• D. Anther and stigma placed at different positions in some flowers

Answer 1

Answer:

B. Production of bisexual flowers

• This increases the homozygosity of the race.

• Continuous inbreeding reduces fertility, production, and immunity of the animals to natural calamities.

• It reduces variations and thus chances of developing adaptations with the ever-changing environment.

• This is known as inbreeding depression.
