The Hitchhiker's Thumb Trait: Dominant or Recessive?

Is the hitchhiker's thumb trait dominant or recessive?

What determines whether the hitchhiker's thumb trait is dominant or recessive?

Answer:

The hitchhiker's thumb can be either dominant or recessive depending on the specific gene controlling it.

The hitchhiker's thumb is a trait that can be either dominant or recessive depending on the specific gene that controls it. In biology, dominant traits are those that are expressed when an individual possesses at least one copy of the gene, while recessive traits are only expressed when an individual has two copies of the gene.

In the case of a hitchhiker's thumb, it can be either dominant or recessive. If the dominant allele is present, an individual will have a hitchhiker's thumb, while the recessive allele will result in a straight thumb. So, to answer the question of whether the hitchhiker's thumb is dominant or recessive, it depends on the specific genetic makeup of the individual.
