Detailed explanation-1: -Genetic Drift Example Consider a population of rabbits with brown fur and white fur, white fur being the dominant allele. Due to genetic drift, only the brown population might remain, with all the white ones eliminated. A couple with brown and blue eyes has children with brown or blue eyes.
Detailed explanation-2: -Genetic drift affects the genetic makeup of the population, but unlike natural selection, through an entirely random process. So although genetic drift is a mechanism of evolution, it doesn’t work to produce adaptations. Read more about: The mechanism of genetic drift, sampling error.
Detailed explanation-3: -Examples of genetic variation include eye color, blood type, camouflage in animals, and leaf modification in plants.
