| How many traits did Gregor Mendel study at a time? | One |
| What mathematical subject did Gregor Mendel use to study the pea plants? | Probability - helped him make predictions about future offspring |
| What is the passing of traits from parents to offspring called? | Inheritance |
| Segments of DNA on a chromosome are called _______________. Alleles Genes | Genes |
| An alternate expression of a gene (there are always 2 of them) is called ____________________. Gene Allele | Allele |
| A chromatid that controls a certain trait is called a ________________. Filial Gene | Gene |
| __________________ occur in pairs because there is one on each homologous chromosome. Allele Genes | Gene |
| The pure bred generation of Mendel's experiment (what he started with) are called _______________________. Filial Parental | Parental |
| The generation from cross breeding the parental generation is called _________________________. Punnet Filial | Filial |
| What principle discusses when the dominant allele masks (or covers up) the recessive allele? Principle of Coverance Principle of Dominance and Recessiveness | Principle of Dominance and Recessiveness |
| What is used to predict the results of a cross without actually crossing the traits? Prudent Square Punnet Square | Punnet Square |
| Which allele (dominant or recessive) uses a capital letter to represent it? | Dominant |
| Which allele (dominant or recessive) uses a lower case letter to represent it? | Recessive |
| A punnet square represents ________ probability for each offspring. 50% 100% | 100% |
| The actual genetic makeup of an organism is called _________________. Genotype Phenotype | Genotype |
| The physical description of a trait is called the ____________________. Genotype Phenotype | Phenotype |
| The ________________________ comes from the genotype. Phenotype Parental | Phenotype |
| A gene that is homozygous dominant looks like __________________. Bb BB bb | BB (2 dominant alleles) |
| A gene that is heterozygous looks like ___________________. Bb BB bb | Bb (One recessive and One dominant allele) |
| A gene that is homozygous recessive look like ___________________. bb Bb BB | bb (2 recessive alleles) |
| A cross involving one trait/one genotype is called ________________. Dihybrid Monohybrid | Monohybrid |
| Using small numbers of individuals to represent large populations of individuals is called ______________________. Presentation Sampling Population Sampling | Population Sampling |
| What is one problem with population sampling? | May not be accurate if small area doesn't have all the characteristics of the large area |
