tounge rolling is a dominant trait, as is free earlobes. if an individual who has attached earlobes and who i?

rolling is dominant (say, R)
non rolling is recessive (say, r)

free earlobes is dominant (say, E)
attached earlobs is recessive (say, e)

P1 who has attached earlobes (ee)
P1 can roll a tongue (Aa or AA). Because the father could not (aa), we know P1 must be Aa

Together, P1 is Aaee

P2 is heterozygous for both AaEe

Possible gametes for P1 - ae (50%) and Ae (50%)
Possible gametes for P2 - AE (25%), Ae (25%), aE (25%), ae (25%)

Possibilites:
Rolling, free - ae+AE, Ae+AE, Ae+aE, each at 50%*25% = 1/8 or 3/8
Rolling, attached - ae+Ae, Ae+Ae, Ae+ae, each at 50%*25% = 1/8 or 3/8
Non-rolling, free - ae+aE, 50%*25% = 1/8
Non-rolling, attached - ae+ae, 50%*25% = 1/8

Phenotype ratio is 3:3:1:1
