12 Questions
What is the primary unit of study in evolutionary processes?
Populations
What is the term for the change in percentages of alleles within a population?
Microevolution
What is the source of genetic variation in a population?
Mutations
What is the process by which alleles move from one population to another?
Gene flow
What is the result of increased genetic variation in a population?
Increased chance of adaptation to changing environments
Which process is most significant in the formation of new species?
Natural selection
What is the primary effect of gene flow on a population?
It changes allele frequencies and increases genetic diversity
Why do grey wolves travel great distances to find a neighboring pack?
To mate with an individual in that pack
What is the result of non-random mating in a population?
It increases the proportion of homozygous individuals
Why do male caribou spar with each other?
To be able to mate with a female in the herd
What is the advantage of self-fertilization in pea plants?
It ensures reproduction if pollination is unsuccessful
What is the effect of inbreeding on a population?
It increases the expression of harmful recessive alleles
Explore the processes that drive evolution within populations, including changes in allele frequencies and genetic variation. Learn how microevolution shapes the gene pool of a population and understand the five key mechanisms that influence evolution. Test your knowledge of evolutionary biology and population genetics!
