|---|---|
| Monk who studied genetics | GREGOR MENDEL |
| Plant Mendel cross-pollinated and studied | PEA |
| When plants self-pollinated, Mendel saw offspring of tall plants were tall and offspring of short plants were sort. He called these offspring ____. | PURE |
| When Mendel cross-pollinated pure tall and pure short plants, all the offspring were ___. | TALL |
| Mendel called cross-pollinated plants _____. | HYBRIDS |
| Hybrid pea plants had: A. both tall parent plants B. both short parent plants C. both tall and short parent plants | BOTH TALL AND SHORT PARENT PLANTS |
| In hybrid plants, what traits are visible? | DOMINANT |
| In hybrid plants, what traits are hidden? | RECESSIVE |
| What is the 4-square diagram is used to show how traits are passed to the next generation? | PUNNETT SQUARE |
| The uppercase letter, such as used by "T" and "t" for tallness, represents _____. | DOMINANT GENE |
| The lowercase letter, such as used by "T" and "t" for tallness represents _____. | RECESSIVE |
| In the Punnett Square, a parent with two dominant genes or "TT" and a parent with two recessive genes or "tt" will have how many hybrid offsping? | FOUR (or all) |
| In the Punnett Square, a parent with two dominant genes or "TT" and a hybrid parent with one dominant and one recessive gene or "Tt" will have how many hybrid or "Tt" offspring? | TWO |
| In the Punnett Square, a parent with two dominant genes or "TT" and a hybrid parent with one dominant and one recessive gene or "Tt" will have how many dominant or "TT" offspring? | NONE |
