Mechanisms of Evolution 2023

Front

What is genetic drift?

Back

Genetic drift is a change in the allele frequency of a population due to random chance.

What mechanism of evolution is demonstrated by bats with longer claws having higher fitness?

Back

Natural Selection is the mechanism of evolution where certain traits become more common in a population because they provide an advantage.

Front

What is mutation in the context of evolution?

Back

Mutation is the process that creates new variations and changes in DNA, leading to the creation of new alleles.

Front

What happens during a mutation?

Back

A mutation is a change in the genetic code that can lead to new traits or abilities.

Front

What is allele frequency?

Back

Allele frequency is a measure of how common a certain allele is in a population.

Front

What is natural selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is gene flow?

Back

Gene flow is the transfer of genetic material between populations, which can increase genetic diversity.

Front

What is the gene pool?

Back

The gene pool is the total collection of genes and their alleles in a population.

Front

What is microevolution?

Back

Microevolution refers to small-scale changes in allele frequencies within a population over time.

Front

What is non-random mating?

Back

Non-random mating occurs when individuals select mates based on specific traits, affecting allele frequencies.
