The genotype that would produce offspring with a Hitchhiker's thumb is 'ww'.
Explicación
## Step 1The problem is about understanding the principles of genetics, specifically the concept of recessive traits. In genetics, traits are determined by genes, which are segments of DNA. Each gene has two alleles, one inherited from each parent. ## Step 2A recessive trait is one that is expressed only when an individual has two copies of the recessive allele. In this case, the recessive trait is having a Hitchhiker's thumb. ## Step 3The genotype of an individual is the set of two alleles they have for a particular trait. In this case, the genotype that would produce offspring with a Hitchhiker's thumb is 'ww', as this genotype has two copies of the recessive allele. ## Step 4The genotypes 'Ww' and 'WW' would not produce offspring with a Hitchhiker's thumb, as they do not have two copies of the recessive allele.
