Tongue rolling is an inherited trait. The ability to roll your tongue is dominant (T) over not being able to rollyour tongue (1).

What's the ratio of the genotypes? (TT:Tt: tt) What's the ratio of the phenotypes? (can roll: cannot roll) what's the probability of offspring that can and cannot roll their tongue?

Tongue rolling is an inherited trait. The ability to roll your tongue is dominant (T) over not being able to roll
your tongue (1). Dad is heterozygous for tongue rolling and mom is homozygous dominant for tongue
rolling.

Draw a Punnett Square on a separate sheet of paper using the parent's
genotypes from above. Complete the Punnett Square to answer the following
questions.
