Suppose your cousin has decided to begin breeding owls. She does some research and finds out that a single gene controls feather color. She really wants her owls to have brown feathers, so she buys two brown owls from a breeder and breeds them together. Imagine her surprise when they have four brown babies and one white baby (who, of course, she names Hedwig)! Using “B” to indicate the dominant allele and “b” to indicate the recessive allele.
