Suppose unattached earlobes are a dominant trait. Phil and Maggie both have unattached earlobes but their daughter, Celia, does
rosijanka [135]

Answer:

The correct option is A. 1/4

Explanation:

Let's try to interpret the results by drawing a punnet square for the cross.

Let's consider E to be the dominant allele and e to be the recessive allele.

The cross can be shown as :

        E       e                                          

E      EE     Ee                                

e       Ee     ee          

The results from the punnet square prove that 1/4  of the offsprings will have a chance to have attached earlobes.
