| Question | Answer |
|---|---|
| Heredity | The passing of traits from parents to offspring |
| Genetics | The scientific study of heredity |
| Traits | physical characteristics |
| Gregor Mendel | Experimented with pea plants to understand the process of heredity |
| Purebred | Name for offspring of many generations that have the same trait |
| pod color, seed shape, flower position | Other traits in garden peas that Mendel studied |
| purebred short | two alleles for short stems |
| purebred tall | two alleles for tall stems |
| hybrid tall | One allele for tall stems and one allele for short stems |
| probability | a number that describes how likely it is that an event will occur |
| BCP | My favorite Day 1 period 1 class this semester |
| predict | Mendel realized that the principles of probability could be used _________the results of genetic crosses. |
| punnett square | A chart that shows all the possible combinations of alleles that can result from a genetic cross is called a _______ ________ |
| phenotypes | An organism's physical appearance, or visible traits |
| genotype | an organism's genetic makeup, or allele combinations |
| homozygous | Describes an organism with two identical alleles for a trait |
| heterozygous | Describes an organism that has two different alleles for a trait. |
| Hybrid | The term Mendel uses to describe heterozygous pea plants. |
| Co-dominance | Means that the alleles are neither dominant nor recessive. |
