Pleiotropy occurs when one gene influences multiple, seemingly unrelated phenotypic traits. A single gene is responsible for pigmentation and hearing.

Answer:

When a single gene is responsible for controlling multiple traits then the gene is said to be pleiotropic.

Explanation:

  • A pleiotropic gene is a gene that controls many functions and thus, a mutation in this single gene is going to show its effect in several traits.
  • Since, the gene responsible for white fur in cats is also responsible for eye colour and hearing and thus, it controls more than one trait and hence, it is pleiotropic.

horrorfan [7]
Hi! I believe that the lasers are used for measuring the earthquakes movement and how much worse it is going to be with the next earthquake. But they would also measure how much force there was and how much more or less there will be. :) Hope this helps. :)
