Answer:
50%, and 0%
Explanation:
Make a chart, and fill it in
a)
_ |E | e
e |Ee | ee
e |Ee | ee
2/4 have Ee, and 2/4 have ee, ee is the attached, so the chance is 2/4, or 50%
b)
hom*zygous means that both letters are the same, so EE, or ee
the mother is EE, while the father is ee
make a table:
_ |E | E
e |Ee | Ee
e |Ee | Ee
As you can see, it's all Ee, so the only possibility is for the child to have detached earlobes, and no attached earlobes are produced (in theory, at least)
