Question
Marfan syndrome is an example of pleiotropy because ________.
all dominant alleles in the three pairs of alleles controlling this disease cause a weakened aorta
one gene causes disproportionately long legs and arms, a weakened aorta, and poor eyesight
many genes cause disproportionately long legs and arms as triggered by the environment
codominant alleles affect more than one genotypic trait
a.all dominant alleles in the three pairs of alleles controlling this disease cause a weakened aorta
b.one gene causes disproportionately long legs and arms, a weakened aorta, and poor eyesight
c.many genes cause disproportionately long legs and arms as triggered by the environment
d.codominant alleles affect more than one genotypic trait
Explanation / Answer
Option b
Note - plieotropy is when one gene control more than one trait of function leading to multiple defect in marfan syndrome.
