Question

jack and jill were brother and sister, but didnt look alike at all. jack had attached earlobes (recessive) and jill had free earlobes (dominant). jill knew her parents were heterozygous for earlobe shape, so she drew the following punnett square:| | e | e ||---|---|---|| e | ee | ee || e | ee | ee |jacks earlobes were different from the rest of the family. which of these answers explains how this happened?○ jack didnt inherit his earlobe shape from his parents. he got his earlobes from his grandma.○ jack got one dominant gene from each parent.○ jack got one recessive gene from each parent.○ jack got one dominant gene from one parent and one recessive gene from the other parent.

Explanation:

Step1: Identify Jack's genotype

Jack has attached earlobes, a recessive trait, so his genotype is $ee$.

Step2: Analyze parental genotypes

Parents are heterozygous ($Ee$), so each can pass $e$.

Step3: Match to correct option

To get $ee$, Jack must inherit $e$ from both parents.

Answer:

Jack got one recessive gene from each parent.
