Question

What process needs to be avoided for carrying of efficient crosses?

(a) Self-pollination

(b) Fertilization

(c) Development of embryo

(d) Pollen tube development

The question was posed to me in exam.

I would like to ask this question from Inheritance of One Gene-1 topic in section Principles of Inheritance and Variation of Biology – Class 12

Answer 1

The correct answer is (a) Self-pollination

To elaborate: Self-pollination leads to fertilization by the pollen from the same flower. A cross desires pollination and fertilization by pollen from a different plant. Hence self-pollination needs to be avoided.
