What will be the ploidy of endosperm and zygote if the cross is made between a 6n female plant and a 4n male plant?
Options:
Answer:
B
Solution:
Endosperm is 3n (triploid) in nature and zygote is 2n (diploid) in nature.
So, for the given case, a plant with 6n makeup will produce a 3n gamete, and plant with 4n makeup will produce a 2n gamete.
A fusion between 3n and 2n gametes would produce a zygote of 5n makeup (3n+2n). And the endosperm would be of 8n makeup (3n+3n+2n).
