If the diploid number of a flowering plant is 36. What would be the chromosome number in its endosperm
Endosperm is triploid [3n] in angiosperm. As 2n=36, n=18
Hence chromosome number in endosperm,3n= 3*18
=54
Due to fusion of a male gamete[n] with secondary nucleus [2n], triploid [3n] PEN(primary endosperm nucleus) is formed.
