Read the following statements carefully regarding apomixis and polyembryony: Statement I: Apomixis is a form of asexual reproduction that mimics sexual reproduction by producing seeds without fertilization. Statement II: In some species of Asteraceae and grasses, a diploid egg cell is formed without reduction division and develops into an embryo without fertilization. Statement III: In Citrus and Mango varieties, the
Options
- AAll statements I, II, III, and IV are correct.
- BOnly statements I, II, and IV are correct.
- COnly statements II and III are incorrect.
- DOnly statements I and III are correct.
Correct answer
B. Only statements I, II, and IV are correct.
Step-by-step solution
Statement I correctly defines apomixis as a form of asexual reproduction that mimics sexual reproduction by producing seeds without the process of fertilization. Statement II is correct as a common mechanism of apomixis observed in some species of Asteraceae and grasses involves the formation of a diploid egg cell without reduction division, which then develops directly into an embryo. Statement III is incorrect because the nucellar cells in Citrus and Mango that divide and protrude into the embryo sac to cause pol
