In shorthorn cattle, pigmentation is controlled by the MGF gene. There are two versions of this gene, which differ from each other by only a single amino acid. If an animal is homozygous for one version of the gene, its hair will be fully pigmented and a solid red color. If the animal is homozygous for the other version of the gene, it doesn't produce pigment in its hair, so the result is an animal with white hair. A breeder crosses a solid red male with a solid white female and finds that the offspring has patches of white and red hairs, which is considered a roan coloration trait Part 1: Based on the information provided, what can you conclude about the pattern of inheritance for this gene for pigmentation in cattle?
Part 2: Explain to the breeder what happened in this cross. Be sure to include both phenotypes and genotypes in your explanation.
