Below are examples of genetic drift. What similarities do you see in the examples? -Many individuals are killed due to a disease that only attacks those with blue eyes, causing blue eyes to become rarer in the area. -An airplane crash introduces the white heron, which loves spotted mackerel, into a population of spotted and unspotted mackerel. Over time, fewer mackerel are born with spots -A man steps on a group of beetles, randomly killing most of the green ones but leaving most of the brown ones alive, resulting in fewer green beetles being produced in the population. -A wildflower population consisting of blue, purple, and pink flowers is subjected to a mudslide that kills most of the blue on es. As time progresses, blue flowers eventually die out, leaving only purple and pink wildflower

Genetic Variation

Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.

Quantitative Genetics

Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
