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)
Hydrogen Bonding in Water (1) The hydrogen bond in water is a dynamic attraction between neighboring water molecules involving one hydrogen atom located between the two oxygen atoms.
When we talk about evolution we come across the process of natural selection. Genetic variation is always required for the natural selection. A change or variation in the genes may help the individuals in a population to better adapt to the environment. Such changes may be brought by mutations or random mating in the population. Such variations help in the survival of the population by allowing them to adapt to changing environmental conditions.
Green algae contain the same carotenoids and chlorophyll a and b as land plants, whereas other algae have different accessory pigments and types of chlorophyll molecules in addition to chlorophyll a. Both green algae and land plants also store carbohydrates as starch.
