If the female flower with genotype Tt undergoes meiosis during gamete formation, it produces two types T and t.Since the nuclei of embryo sac are haploid they might either be T or t. So when the two nuclei fuse to form secondary nucleus the genotype of it might be TT or Tt or tt . After the fusion with the male gamete(which produces a single type of gamete T) the genotype of endosperm will be TTT or TTt or Ttt.

Same is the case is with embryo As there are two types of gametes from female parent T and t ,the genotype of the embryo will be TT or Tt
