Some plant species produce male and female individuals in which the males have an XY genotype and the females have an XX genotype. After double fertilization, what would be the genotypes of the embryos and endosperm nuclei?

Question

Quizplus · Accepted Answer

Double fertilization in plants results in the formation of an embryo and endosperm. The embryo is formed from the fusion of one sperm cell with the egg cell, resulting in either XX (female) or XY (male) genotypes. The endosperm is formed from the fusion of a second sperm cell with two polar nuclei, typically resulting in a triploid (3n) genotype. Therefore, for a female embryo (XX), the endosperm would be XXX, and for a male embryo (XY), the endosperm would be XXY.
