Explanation:
Detailed explanation-1: -The ploidy of the male plant is 2n and has 24 chromosomes. The ploidy of the female plant is 2n and has 24. Hence the embryo will be diploid and its ploidy will be 24. Since the angiospermic endosperm is triploid, its ploidy will be 3n= 3x12 (n=24/2)= 36.
Detailed explanation-2: -Plum gametes have 24 chromosomes. Gametes are haploid, meaning that they have half the amount of chromosomes compared to a diploid somatic cell.
