Answer:
Option B is correct
Explanation:
Given -
"Ability to taste the chemical phenylthiocarbamide" is autosomal dominant while its inability is recessive.
Autosomal dominant means that even if one l
Let the allele for dominant trait i.e "Ability to taste the chemical phenylthiocarbamide" be represented by "T"
and the allele for recessive trait i.e "Inability to taste the chemical phenylthiocarbamide" be represented by "t"
Genotype of a taster woman with a nontaster father is Tt
Genotype of a taster man who in a previous marriage had a nontaster daughter is also Tt
Tt * Tt
TT, Tt, Tt, tt
Therefore probability of being a taster is , and the probability of being a nontaster is
Probability that their first child will be a taster girl is equal to
Probability of being a taster Probability of being a girl
Thus, option B is correct
