Elizabeth is married to John and they have four children. Elizabeth has a straight nose (recessive) and is able to roll her tongue (dominant). John is also able to roll his tongue, but he has a convex nose (dominant). Of their four children, Ellen is just like her father, and Dan is just like his mother. The other children, Anne has a convex nose, and Peter has a straight nose and neither of them can roll their tongues.
Please answer the following questions about this family.
R=convex Roman nose, r=straight
T=tongue roller, t=unable to roll
1. What are the genotypes of Elizabeth and John?
2. Elizabeth’s father was a straight-nosed roller, while her mother was a convex-nosed non-roller. What can you figure out about their geno types?
Elizabeth=rrTt
3. John’s fatherwas a straight-nosed roller, while his mother was a convex-nosed roller. What can you determine about their genotypes?
John=Rrtt
