Question

Marfan's syndrome is the result of inheriting a single allele. Individuals with Marfan's syndrome are tall and long-limbed, and have both cardiovascular and eye defects. The inheritance of Marfan's syndrome is an example of?

Answer 1

Pleiotropy

Step-by-step explanation:

Marfan syndrome is an example of pleiotropy, which can be defined as the phenomenon in which a pair of allele genes conditions the appearance of several traits in the same organism.

All of these traits occur through the action of only one pair of genes, so pleiotropy shows that the idea that each gene affects only one trait is not always valid.

In other words, a pleiotropic gene can have an effect on several phenotypes at the same time, due to the fact that the mutated gene is used by a group of cells (or targets) that have the same signaling function.
