Answer 5

So they inherited genotype EE or ee?

if it's E_ anything then it's detached

only if he inherited ee, will his earlobes be not detached

Answer 6

wait is this "A child inherits genes with the genotype: EE and ee" saying that those were the parents genotypes?

Answer 7

yea i think

Answer 8

oh, that's some really bad wording.

it's 100% because no matter what, he will get E from one parent, thus dominant phenotype will be expressed

Answer 9

i think its 50%

Answer 10

How so?

Answer 11

Answer 13

Okay, all that is saying that all of the offspring will be Ee

because the E allele is present the dominant phenotype will be expressed - the dominant phenotype is detached earlobes

Answer 14

so what do you think it is?
