PLEASE HELPPP
Please help me draw Punnett square and answer questions
Betty-Lou can roll her tongue. Her mother (who is pregnant) can roll her tongue, but her father cannot. Her
father's two sisters can both roll their tongues. Betty-Lou's brother can roll his tongue, but her two sisters cannot.
Predict the genotypes/phenotypes for Betty-Lou's paternal grandparents. What is the chance of Betty-Lou's new
sibling being able to roll his/her tongue? Show your work with a Punnett square
