Biology Undergraduates’ Misconceptions about Genetic Drift
Type: Empirical
Data collection method: Interview
Number of subjects, range: Large — 31 or more
Grade and age of subjects: Adult — over 18 years
Genetics
-
Genetic drift [is when it’s the same species but different characteristics.
-
Genetic drift because both species have distinctive commonalities.
-
Genetic drift is where the amount of present alleles changes gradually over time.
-
Genetic drift is a change in genes over time.
-
Genetic drift is the passing down of traits while natural selection does not have anything to do with genetics.
Evolution
-
As the butterflies adapt to their new habitat.
they physically change in order to survive due to genetic drift.
-
The evolution of the two butterflies is genetic drift because they developed to
their surroundings.
-
Genetic drift occurred when certain butterflies with each gene and characteristics came together in a certain spot and they mated forming new types of butterflies.
-
Genetic drift is] the genetic changes that occur when a population is not under selection.
Associating Genetic Drift with Other Evolutionary Mechanisms
- Genetic drift occurs when due to random mutations, the genetic structure can change over time.
-
The definition of genetic drift is random chance mutation.
-
Genetic drift is a chance occurrence that brings genes into a population.
-
Genetic drift occurs to eliminate the less adaptable trait that is not well-suitable to the environment.
-
Genetic drift is] the process of changing allele frequencies within a population.
Associating Genetic Drift with Population Boundaries
- Genetic drift occurs due to] isolation of a population or species by whatever means.
- Genetic drift occurs when a sect of a species is separated from the other and changes to adapt to its new environment.
Developing Genetic Drift Comprehension
- Genetic drift involves a natural disaster that dramatically changes the genes in that area.
-
Genetic drift is genetics in smaller populations.
