| What is an example of genetic drift? | Certain organisms dying by chance, which changes the gene pool.
🗑

| What are the five factors that cause populations to evolve? | Genetic Drift, Gene Flow, Mutation, Sexual Selection, Natural Selection.
🗑
|

| What is an example of Mutation? | A new allele randomly appears among a certain species.
🗑
|
||||
| What is an example of sexual selection? | A peacock's feathers are more appealing to females so it has a higher chance to reproduce.
🗑
|
||||
| Why aren't mutations in non-reproductive cells a source of genetic variation? | Non-reproductive cells have nothing to do with reproduction so the mutation will not be passed down to offspring.
🗑
|
||||
| What are two main sources of genetic variation in a population’s gene pool? | mutations and gene reformation
🗑
|
||||
| What are the three types of natural selection? | directional selection, stabilizing selection, or disruptive selection.
🗑
|
||||
| what is a gene pool? | variation of genes in a population
🗑
|
||||
| What is gene flow, and how does it relate to what is happening to this population? | A gene flow is the transfer of alleles or genes from one population to another.
🗑
|
||||
| If a drought happened in a population, would the frequency increase or decrease? | The frequency would decrease.
🗑
|
||||
| If a population kept on reproducing offspring, would the frequency increase or decrease? | The frequency would increase.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
