Question

This question refers to the gene for the ability to taste PTC.One member of a couple is homozygous dominant and the other is a non-taster of PTC.Answer the questions below regarding the expected offspring.4a. What is the percentage chance of an offspring of this couple being a Taster of PTC? (1 mark).*note* Please enter numbers only - up to a maximum of 3 digits (0-100)4b. What is the percentage chance of an offspring of this couple being Heterozygous for the allele? (1 mark).*note* Please enter numbers only - up to a maximum of 3 digits (0-10

Answer 1

As the trait is dominat, an heterozygous individual will be a taster or PTC.

Being the parents TT and tt, 100% of the offspring will be a taster and heterozygous. (100% for both answers)
