Approximately 40 percent of cats with white fur and blue eyes are completely deaf. In cats with one blue eye and one eye of a di
fferent color, deafness occurs only on the blue-eyed side. White fur, blue eyes, and deafness are linked to a single pleiotropic gene in cats. Based on the information above, it can be concluded that pleiotropy occurs when A. one trait is influenced by many genes. B. a trait is influenced by both genes and environment. C. one gene influences multiple traits. D. a trait is not influenced by genes.
Pleiotropy can be defined as a phenomenon in genetics whereby one particular gene in the affects or influences multiple phenotypic traits expressed in the human body.
Pleiotropy can result in the occurrence of disorders in a human body. An example of Pleiotropy is Phenylketonuria.
Phenylketonuria is a human or animal disorder occurs due to the build of the amino acid phenylalanine in the body. This could result serious neurological to the brain such as seizures, damages to the intellectual capacity of the brain e.t.c.
Another symptom of Phenylketonuria is the presence of fair skin and blue eyes because the body was unable to convert or transform phenylalanine to melanin (which gives pigmentation to the body)
Cancer cells reproduce the same way the other cells reproduce. The difference between cancer cells and others is that their reproduction is uncontrollable. They constantly go through the cell cycle and they reproduce. Two ways cell reproductions are meiosis and mitosis. DNA duplicates itself. Cancer is incessantly receiving messages.
