| Question | Answer |
|---|---|
| What did Gregor Mendel do? | He studied genetics by CROSS POLLINATING PEA PLANTS |
| What do we call factors that control traits? | GENES! |
| If an organism has 2 different alleles for a trait we call that individual a | hybrid (or we say heterozygous) |
| What does TT mean? | Two capital letters means 2 DOMINANT alleles |
| What does Tt mean? | One dominant allele and one recessive allele |
| What does a Punnett Square show? | The possible outcomes of a genetic cross |
| What is a phenotype? | An organisms physical appearance. (In other words....it is what we can see) |
| What does CODOMINANCE mean? | Neither allele is dominant. They both show up. |
| What do we call different forms of a gene? | ALLELES |
| What is a genotype? | Its actual genetic make-up. (It's 2 letters) |
| If an organism has 2 identical alleles for a trait we call it | Homozygous or purebred |
| What is a pedigree chart used for? | Tracking a particular trait through multiple generations of a family |
| Which human genetic disorder results in abnormally shaped blood cells? | Sickle-cell disease |
| In a pedigree, what does a circle represent? | a female |
| In a pedigree, what does a square represent? | a male |
| What does a blackened circle represent? | A female who has the trait |
| What does a blackened square represent? | A male who has the trait |
| How is a carrier female shown? | The circle is only half blackened. |
| Remember to practice your Punnett squares!! The test has a dominant/recessive, an incomplete dominance, and a codominance Punnett square! |
