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

Mutation - Mutation is defined as the sudden change or alteration in the DNA sequence. Mutation is caused by mistakes which occurs during the copying of DNA in cell division.
Osteogenesis imperfecta - Osteogenesis imperfecta means imperfect bone formation. It is group of genetic disorder. This condition mainly affects the bones of the body. in this condition, bones of the body become weak. OI has many symptoms. These are:
1. This disease affects the gene that makes the collagen
2. Weak bones
