Determine the results from a cross of a mother who is heterozygous for tongue rolling with a father who is homozygous recessive

In order to determine the results from a father who is homozygous recessive for the tongue rolling trait, T, and a mother who is heterozygous for the trait, a Punett square can be used to determine both the resulting genotype (allele combination) and phenotype (observable characteristics). The results are 50% Tt and 50% tt. Thus, the cross would result to 1:1 ratio of tongue rolling to non-tongue rolling offsprings. 

My pigs teeth have already came in years ago, with my first molars, and my second molars are pretty much in. my wisdom teeth will be unable to come in, but i'm getting those out on monday.
