Alleles of a single gene control whether individuals have a "hitchhiker's thumb" or "straight thumb." You are studying the inheritance of hitchhiker's thumb (straight thumb is dominant) in your family. Assuming that this trait is inherited on an autosome (ie, not a sex-chromosome), please answer which of the following outcomes ARE POSSIBLE under normal circumstances. (Choose all that apply.) 1) Two parents have straight thumb, but they have a child with hitchhiker's thumb. 2) Two parents have hitchhiker's thumb, but they have a child with straight thumb. 3) Mother has straight thumb, father has hitchhiker's thumb, child is homozygous dominant for the allele. 4) Mother has straight thumb, father has hitchhiker's thumb. They have one child with straight thumb, another child with hitchhiker's thumb.
