Vedclass · Answer

(C) In angiosperms,the endosperm is formed by the fusion of two polar nuclei (from the female gametophyte) and one male gamete (from the pollen grain).This process is known as triple fusion,resulting in a triploid $(3n)$ structure.Given the endosperm genotype is $ZZA$,it implies that the two polar nuclei contributed $ZZ$ and the male gamete contributed $A$.Since the polar nuclei are derived from the female plant,the female plant must have a genotype of $ZZ$.Since the male gamete is derived from the male plant,the male plant must have a genotype of $AA$.

The genotype of the endosperm is $ZZA$. Find out the genotype of the male and female plant,respectively.
