Based on the described phenotype, determine the genotype(s). In humans, having a Hitchhiker's thumb is a recessive trait. Which genotype(s) would produce offspring have a Hitchhiker t thumb? ww ww ww

## Step 1<br />The problem is about understanding the inheritance of traits in humans, specifically the trait of having a Hitchhiker's thumb. This trait is described as recessive, which means that an individual must inherit two copies of the recessive allele (one from each parent) to express the trait.<br /><br />## Step 2<br />In genetics, alleles are different forms of a gene. For a recessive trait, the individual must have two copies of the recessive allele to express the trait. This is because the presence of a dominant allele would mask the effect of the recessive allele.<br /><br />## Step 3<br />In this case, the recessive allele is represented by 'w'. Therefore, an individual would need to have the genotype 'ww' to express the trait of having a Hitchhiker's thumb.
