Question

multiple choice 1 point
if a mom with ear lobes that were unattached at the bottom (ee) had a child with the father who had attached ear lobes (ee). what is the chance that the kids would have
unattached ear lobes? hint: (do the punnett square first and then count how many end up being ee?)

Explanation:

Step1: Determine gametes

The mother (Ee) can produce gametes E and e. The father (ee) can produce gamete e.

Step2: Create Punnett square

	E	e
e	Ee	ee

Step3: Calculate probability

There are 4 possible offspring genotypes. 2 of them are Ee (unattached ear lobes). The probability is $\frac{2}{4}=\frac{1}{2}$.

Answer:

The chance that the kids would have unattached ear lobes is $\frac{1}{2}$ or 50%.
