Mechanisms of Evolution Flashcards
Natural Selection can also be described as?
Survival of the Fittest
TRUE or FALSE:
Fitness is the ability to survive long enough to reproduce
True
This mode of Natural Selection states that the intermediate phenotype is the fittest
Stabilizing
This mode of Natural Selection states that only one extreme phenotype is the fittest
Directional
This mode of Natural Selection states that two or more extreme phenotypes are the fittest.
Disruptive
This kind of Natural Selection results from variation in the ability to obtain mates (Directly influences reproductive success)
Sexual Selection
This shows difference in appearance between males and females
Sexual Dimorphism
This is a type of sexual selection where members of the same species fight to mate the opposite sex.
Type 1
This shows a change in an organism’s DNA sequence and introduces a new allele to a population.
Mutation
This kind of mating shows organisms prefers to mate either with the same genotype or different genotype.
Non-Random Mating
This is when a population either gain or lose alleles when species move into or out of the population.
Gene Flow
This evolution shows a change in allele frequencies purely by chance or at random. (Eliminates alleles from a population)
Genetic Drift
This kind of Genetic Drift occurs when a small group of individuals leaves its home population to establish an new, isolated settlement.
Founder Effect
This type of Genetic Drift shows when the population’s size drops rapidly over a short period of time due to a disaster.
Bottleneck Effect
