question 35

Multiple Choice

Unattached earlobes (EE or Ee) are dominant over attached earlobes (ee) . A couple has unattached earlobes. Both notice that one of their parents on both sides have attached earlobes (ee) . Therefore, they correctly assume that they are carriers for attached earlobes (Ee) . If the couple proceeds to have four children, then

• A) they can be certain that three will be heterozygous and one homozygous recessive.
• B) if the first three are heterozygous, the fourth must be homozygous recessive.
• C) the children must repeat the grandparents' genotype (Ee).
• D) all children must have unattached earlobes since both parents possess the dominant gene for it.
• E) two heterozygous, one homozygous dominant, and one homozygous recessive is a likely outcome, but all genotype ratios are possible.
