Rudоlph the Red-Nоsed Reindeer hаd а very shiny nоse. The shine, or bioluminescence, is the result of а mutation in a single gene. Geneticists at the North Pole are interested in this gene, so they construct a pedigree for Rudolph and Clarice and their descendants. This tree is shown above. Circles are XX females; squares are XY males. Shaded individuals have bioluminescent noses; unshaded individuals have wild-type non-bioluminescent noses. Bioluminescence appears to be [b] to the wild-type, non-bioluminescent nose. The gene that determines nose bioluminescence appears to be [a]. If this were a real population of reindeer, why would bioluminescence have appeared? [c]
