Question

The ability to roll one’s tongue is a genetic trait due to a dominant allele “R”. Construct a Punnett square to predict the genotypes and phenotypes that result when a man who can roll his tongue (RR) and a woman who cannot roll her tongue (rr) have a child.

Answer 1

Use the Punnett square that you have constructed to answer the following
d) List the different genotypes that are present? … … … … … … … …
e) Describe the different phenotypes that are present? … … … … … … … …
f) What is the likelihood of the offspring being heterozygous?

Answer 2

The Fi will be 100% Rr. Draw th Punnet square here and I'll take a look.
