Test your knowledge on mechanisms like genetic drift, gene flow, and selection influencing population genetics. Explore evolution's intricacies.
#1
Which of the following is a mechanism of evolution?
Natural selection
Photosynthesis
Mitosis
Osmosis
#2
What is meant by genetic variation?
The presence of different alleles in a population
The number of individuals in a population
The number of generations in a population
The proportion of individuals with a particular genotype in a population
#3
What does genetic drift refer to in population genetics?
The movement of individuals between populations
The random fluctuation of allele frequencies in a population
The deliberate manipulation of genes in a laboratory setting
The process of natural selection acting on a population
#4
What is a gene flow?
The transfer of genes between populations
The process of mutation
The elimination of individuals from a population
The process of artificial selection
#5
Which of the following is an example of a genetic bottleneck?
A sudden decrease in population size due to a natural disaster
A gradual increase in population size due to immigration
A constant population size over time
A population with diverse genetic variations
#6
What is meant by the term 'allele frequency'?
The proportion of individuals with a particular genotype in a population
The number of alleles in a population
The total number of individuals in a population
The number of generations in a population
#7
What role does mutation play in evolution?
Introduces new genetic variation into populations
Stabilizes allele frequencies
Decreases genetic diversity
Reduces adaptation
#8
What is the founder effect?
A type of genetic drift where a small group establishes a new population
The introduction of foreign genes into a population
The process of natural selection in founder species
The formation of new species in isolated environments
#9
What is the Hardy-Weinberg equilibrium?
A state where allele frequencies in a population remain constant over generations
A type of genetic drift
A process of genetic mutation
A mechanism of natural selection
#10
What is directional selection?
A form of natural selection where extreme phenotypes are favored over intermediate phenotypes
A type of genetic drift
A process of genetic mutation
A mechanism of artificial selection
#11
What is the effect of genetic drift on small populations?
Genetic drift has a minimal effect on small populations
Genetic drift increases genetic diversity in small populations
Genetic drift can lead to significant changes in allele frequencies
Genetic drift decreases mutation rates in small populations
#12
What is the difference between gene flow and genetic drift?
Gene flow involves the movement of individuals between populations, while genetic drift refers to random changes in allele frequencies
Gene flow leads to a decrease in genetic diversity, while genetic drift increases genetic diversity
Gene flow occurs only in large populations, while genetic drift occurs only in small populations
Gene flow and genetic drift are synonymous terms in population genetics
