Question

39.) A female plant with the ploidy level as 8n is crossed with a male plant with the ploidy level as 4n in an experiment. The ploidy of endosperm after double fertilisation would be ​

Answer 1

Answer:

Explanation:

Endosperm is formed by the fusion of polar nuclei and male gamete. This discussion on If 6N female plant is crossed with a 4N male plant then the ploidy level of endosperm cell would be:- A-3N B-9N C-10N D-8N Correct answer is 8N , but can you explain it? is done on EduRev Study Group by NEET Students.

Answer 2

Answer:

The answer is 10n

because after meiosis female plant will have 4n ploidy & male plant will have 2n ploidy

so the ploidy of endosperm will be 2×(ploidy of female plant after meiosis) + ploidy of male plant after meiosis i e = 2×4n + 2n = 10n
