Question

Detached earlobes are dominant. If a mother has the genotype Ee and a father have the genotype Ee. What is the chance that their child will have detached earlobes? 1. 25% 2. 50% 3. 75% 4. 100%

Answer 1

There is an EE possibility, 2 Ee's and 1 ee. For the earlobes to be not detached, it would have to be ee, as attached earlobes are recessive. and 1 out of 4 options is ee, so 3 out of 4 options would lead to detached earlobes

3. 75%
