We can determine the dominance relationship between spotted and solid color traits by analyzing the offspring obtained from mating. If the spotted trait is dominant, we expect to observe more spotted rabbits than solid-colored rabbits among the offspring.
In this case, the man obtained 32 spotted and 10 solid color rabbits. This result supports the dominance of the spotted trait. If the solid color trait were dominant, we would expect to see a higher proportion of solid-colored rabbits among the offspring.
Therefore, we can conclude that the spotted trait is dominant over the solid color trait in this case.
