Question

Detached earlobes are dominant. If a mother has the genotype Ee and a father has the genotype EE. What is the chance that their child will have detached earlobes? 25% chance 50% chance 75% chance 100% chance

Answer 1

You must make a Punnet square.
 
     E    E
E EE    EE
 
e  Ee    Ee
(I can't make it, but this is what you fill in)

As you can see, there's two EE and two Ee. Each still has at least one dominant E, so all are dominant. Your answer is a 100% chance they'll have detached earlobes.
