Question

What is pleiotropy and. Explain it in detail ?

Answer 1

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. For example, phenylketonuria is a disease caused by pleiotropy.

Answer 2

here are many different mutations that occur during growth in organisms. Many times, these mutations can be passed on and will occur in such a way as to be beneficial to the organism. Sometimes, they are not. We will be looking at one such type of mutation here. A mutation is any sort of genetic alteration that causes a change in the phenotype or expression of that gene. Sometimes we see genetic changes and phenotype changes not from a mutation, but from a gene controlling multiple traits. This is called pleiotropy. As stated, pleiotropy is where one gene winds up controlling multiple phenotypic traits in the organism.An example of pleiotropy is phenylketonuria, an inherited disorder that affects the level of phenylalanine in the body. Phenylalanine is an amino acid that can be obtained from food. Phenylketonuria causes this amino acid to increase in amount in the body, which can be very dangerous.
