|---|---|---|---|---|---|
| Allele | The different forms or versions of a trait. Ex: brown versus blue eyes, short versus tall plant (represented by a letter)
🗑

||||
| Cross-pollination | Pollen form one flower lands on the pistil of a different flower
🗑
|
||||
| Dominant Allele | an allele whose trait always shows up when the allele is present (represented by a capital letter)
🗑
|
||||
| F1 generation | Offspring of the P generation *all are hybrids with heterozygous alleles
🗑

||||
| Purebred | An organism that ALWAYS produces offspring with the same form of a trait as the parents
🗑
|
||||
| Recessive Allele | An allele that is masked (hidden) when a dominant allele is present (represented by a lowercase letter)
🗑
|
||||
| Self-Pollination | Pollen form one flower land on the pistil of the same flower
🗑
|

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.
