🗑
|
||||
| Gene(s) | Traits that you inherit from your parents.
🗑
|
||||
| Genotype | the genetic makeup of an organism or group of organisms with reference to a single trait, set of traits, or an entire complex of traits.

| Heredity | The transferring of genetics from parent to offspring.
🗑

| Trait(s) | a distinguishing characteristic or quality, especially of one's personal nature
🗑
|
||||
| Describe the significance if Mendel's work with pea plants | He was the first to figure it out in the timeline he was in.
🗑
|
||||
| Describe the difference between Phenotype and Genotype and how a punnett square can help with probability of inheriting certain traits. | Genotype is what you see on the outside and Phenotype is what you don't see.

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.
