EVOLUTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How does the middle finger represent mutations?
A
it has an “m” within the fingerprint and that “m” stands for mutations
B
it doesn’t
C
because it is closest to the pointer finger
D
because it doesn’t like the thumb
Explanation: 

Detailed explanation-1: -From TEDEd, there’s a five finger trick for understanding and remembering the five processes-small population, non-random mating, mutations, gene flow, adaptation-that impact evolution (ie. the changes in the gene pool of a population from generation to generation).

Detailed explanation-2: -There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.

Detailed explanation-3: -Genetic drift is change in allele frequencies in a population from generation to generation that occurs due to chance events. To be more exact, genetic drift is change due to “sampling error” in selecting the alleles for the next generation from the gene pool of the current generation.

Detailed explanation-4: -Microevolution is defined as changes in the frequency of a gene in a population. These are subtle changes that can occur in very short periods of time, and may not be visible to a casual observer.
