people with osteogenesis imperfecta have a dominant mutation in one of the two genes that produce type 1 collagen. people with OI have weak bones, bkuish color in teh whites of eyes, and a variety of afflictions that cause weakness in their joint and teeth. However, some people can carry the mutation but have no symptoms. Thus, families can unknowingly transmit the mutation but does not express the OI phenotype. This is an example of which of the following? a. incomplete penetrance b. variable expressivity c. epistasis d. incomplete dominance
