Detached earlobes are dominant. A child inherits genes with the genotype: E and E. What is the chance that they will have detached earlobes?

100% chance
75% chance
50% chance
25% chance

Answer 1

@TheWaffleBRO can you please help me

Answer 2

Is there an option for 0%?

Answer 3

I found this here: https://answers.yahoo.com/question/index?qid=20120413122314AAQOG6e

It is 0%, but I'd like to explain why.
It is customary to use lower case letters to express the recessive gene, and your example has a child with two recessive genes for this trait, ee. This means that he or she will have the recessive phenotype, or attached lobes, because he doesn't have any dominant genes for detached lobes. If he were Ee or EE, he would have detached lobes; ee means two recessive alleles, meaning attached lobes.

Answer 4

nut there is not a choice for 0%

Answer 5

@Mycat4556 the answer is 100% chance

Answer 6

oh I got it, it would be 100% because the E's are in caps so it wouldn't be 0% it would be the opposite

Answer 7

Yes, exactly.
