🗑
|
||||

🗑
|
||||
| Adaptation | A(n) ___ is a trait that helps an organism survive and reproduce

| Dominant | A trait seen in each gereration is ___
🗑
|
||||
| Pea | Mendel worked with ___ plants to learn about heredity.

🗑
|
||||
| External | The temperature in which an organism lives is an example of a(n) ___ environmental influence
🗑
|
||||
| Extinction | Sometimes, ___ occurs because of the destrution of a habitat
🗑
|

| Alfred Russell Wallace | theory: evolution by natural selection
🗑
|
||||
| Gregor Mendel | theory: principle of dominance
🗑
|
||||
| Reginald C. Punnett | theory: Punnett squares
🗑
|
||||
| Mendel's law | alleles for 1 trait do not have an affect on how alleles fora another trait are inherited
🗑
|
||||
| Traits | features an organism inherits from its parents
🗑
|
||||
| Dominant | these alleles show their effect on the phenotype whenever they are present in the genotype
🗑
|
||||
| Phenootype | combination of actual genetic makeup and the environmental effect on that makeup
🗑
|
||||
| Genotype | an organism's genetic makeup
🗑
|
||||
| genetics | science of heredity
🗑
|
||||
| extinction | the demise of an entire species
🗑
|
||||
| mutation | change in DNA that forms new alleles
🗑
|
||||
| evolution | change in the genetics of a species over time
🗑
|
||||
| natual selection | organisms that are better suited to their environment survive and reproduce at a greater rate than organisms that are not
🗑
|
||||
| adaptive radiation | production of several specties from one ancestral species is called __
🗑
|
||||
| What happens when a species overproduce offspring? | food and other resources are limited so many individuals of a species will not survive to reproduce
🗑
|
||||
| Suppose a variation makes an individual member of a species better adapted to its environment, how might that variation affect the individual's reproduction? | If the variation makes the individual member better adapted the environment, then it will more likely survive to reproduce offspring.
🗑
|
||||
| How does the environment "select" organisms? | The environment "selects" organisms that are better adaptedto their environment thus have a better chance to survive and reproduce.
🗑
|
||||
| How do helpful variations accumulate in a species over time? | Helpful variations accumulate through natural selection, as the organisms that are better adapted th their environment reproduce offspring with the same variations.
🗑
|
||||
| Why can only the traits controlled by genes be acted upon by natural selection? | Only genes are passed from parents to their offspring.
🗑
|
||||
| How might the isolation of a group result in a new species? | If a group is isolated from the rest of the species long enough to evolve different traits, a new specties could evolve.
🗑

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.
