The genotypes that would produce offspring with mid-finger hair are Hh and HH.
Explicación
## Step 1The problem involves understanding the principles of genetics, specifically the concept of dominance. In this case, mid-finger hair is dominant over no mid-finger hair. This means that even if an individual has only one copy of the dominant gene (H), they will have mid-finger hair. This is because the presence of a single dominant gene is enough to express the dominant trait.## Step 2The genotype of an individual is the set of genes they possess. In this case, the genotypes that would produce offspring with mid-finger hair are those that contain at least one dominant gene (H). ## Step 3The possible genotypes that would produce offspring with mid-finger hair are:- Hh: This genotype contains one dominant gene (H) and one recessive gene (h). The presence of the dominant gene means that the individual will have mid-finger hair.- HH: This genotype contains two dominant genes (H). Again, the presence of the dominant gene means that the individual will have mid-finger hair.## Step 4The genotype hh would not produce offspring with mid-finger hair because it contains two recessive genes. The presence of two recessive genes means that the individual will not have mid-finger hair.
