Question

Write a note on pleiotropy

Answer 1

Answer:

Pleiotropy occurs when one gene will code and control the phenotype or expression of several different and unrelated traits. Pleiotropy is most often a bad thing, as many diseases are due to a gene controlling so many traits at once.

Answer 2

Answer:

Pleiotropy occurs when one gene influences two or more seemingly unrelated phenotypic traits. Therefore, a mutation in a pleiotropic gene may have an effect on several traits simultaneously due to the gene coding for a product used by a myriad of cells or different targets that have the same signaling function.
