702 - Nat Selection

|---|---|---|---|---|---|
| Artificial selection - | show 🗑
|
||||
| show | when individuals that have advantageous traits survive and reproduce at higher rates than individuals without those traits
this causes the species to evolve
🗑
|
||||
| show | overproduction, genetic variation, and competition
more offspring are produced than can survive; some have genetic traits that help them survive; these advantageous traits cause them to outcompete those without those traits
🗑
|
||||
| show | genetic differences
🗑
|
||||
| Competition - | show 🗑
|
||||
| show | A trait that helps an organism survive and reproduce
🗑
|
||||
| Galapagos finches - | show 🗑
|
||||
| show | how common an allele is in a population
🗑
|
||||
| Mutations - | show 🗑
|
||||
| Sexual reproduction - | show 🗑
|
||||
| show | Formation of new species
🗑
|
||||
| species - | show 🗑
|
||||
| show | can survive
🗑
|
||||
| fertile - | show 🗑
|
||||
| show | when populations of the same species are physically separated from each other
this prevents them from mating
as mutations build up in each population, they can become so different that they become different species
🗑
|
||||
| Adaptive radiation - | show 🗑
|
||||
| types of natural selection - | show 🗑
|
||||
| show | occurs when natural selection favors an extreme version of a trait
example: favoring long tails over short tails
🗑
|
||||
| Stabilizing selection - | show 🗑
|
||||
| Disruptive selection - | show 🗑

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.
