Persons with Marfan syndrome have disproportionately long arms, legs, hands, and feet, a weakened aorta, and poor eyesight.

Question
Persons with Marfan syndrome have disproportionately long arms, legs, hands, and feet, a weakened aorta, and poor eyesight. All of these characteristics are due to a mutated gene (FBN1) on chromosome 15 that ordinarily specifies a functional protein called flbrillin. This is an example of _____.Group of answer choicespolygenicpleiotropycodominanceepistasismultifactorial
Solution
This is an example of pleiotropy. Pleiotropy occurs when one gene influences multiple, seemingly unrelated phenotypic traits, an example of which is the Marfan syndrome where the mutation of a single gene (FBN1) affects the person's height, eyesight, and even cardiovascular health.
