a. State the expected genotype(s) of their children.
b. State what could have been the genotype(s) of this female's mother?
*Start with the genotypes of the parents and then form the gametes of the parents.

say the dominant allele (taster) is T, the recessive (non-taster) is t
the non-taster male has genotype tt
the taster female has genotype Tt, because her father was non-taster (genotype tt), and she needs one T to be a taster.
Their children can be Tt or tt , with 50% probability for either.
the female's mother had one T allele which she passed to her daughter, and that is all we know of her. Her grnotype could have been Tt or TT.
