Gendrift: Function, Task & Diseases

Gendrift is a change in allele frequency within a gene pool of a population. In this context, gene drift is usually triggered by a random event, such as a natural disaster, the shifting of continental plates, or the eruption of volcanoes. Thus, gene drift represents an evolutionary factor. What is gendrift? Gendrift represents an important … Gendrift: Function, Task & Diseases

Erythrocyte Osmotic Resistance: Function, Role & Diseases

Red cell osmotic resistance is a measure of how strongly the membranes surrounding red cells resist an osmotic pressure gradient. A partial osmotic pressure develops at the semipermeable membranes of erythrocytes when they are surrounded by a saline solution that is below their own (physiological) salt concentration of 0.9 percent. Red blood cells absorb water … Erythrocyte Osmotic Resistance: Function, Role & Diseases
