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.

To read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA. These RNA copies can then used to direct protein synthesis, but they can also be used directly as parts of ribosomes or spliceosomes.
