Question

Choose only one of these! Discuss the inheritance pattern, populations commonly found in, phenotypes, cellular physiology, and “molecular” stories for: Red-green color blindness, Tay Sachs, Cystic fibrosis, or Hypercholesterolemia.

Answer 1

Phenotype:

Etymology of Phenotype:
The term phenotype came from the Latin phaeno- , from Greek phaino, meaning “shining”, from phaínein, meaning “to shine”, “to appear”, “to show”, and -type from “typos”.

Definition:

The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior.

Another definition is phenotype is the state of an organsim resulting from interations between genes, environment, disease, molecular mechanisms, and chance.

An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

Due to the influence of environmental factors, organisms with identical genotypes, such as identical twins, ultimately express nonidentical phenotypes because each organism encounters unique environmental influences as it develops.

Examples of phenotypes include height, wing length, and hair color.
Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.

• Why Phenotype matching is important?

It is important, because it allows differential behavior toward previously unmet animals.

Usually, the phenotypes used in phenotype matching are called cues, rather than signals, because there is some question as to whether evolution has shaped the phenotype for its communicatory function.
