Term used to describe a genetic cross involving one trait | Monohybrid
|
What are the alternate forms of a gene called? | Alleles
| Chart used to show the expected outcomes of a genetic cross | Punnet Square
| Genetic makeup of an organism | Genotype
| Genotype that consists of two of the same alleles for a trait | Homozygous
| An organism's physical appearance | phenotype
| An allele that masks the presence of another | Dominant
| Genotype that consists of two different alleles for a trait | Heterozygous
| Expected percentage of tall offspring if you cross two plants that are heterozygous tall | 75%
| Examples of polygenic traits | Height, Eye color, Hair color, Skin color
| The law of _________________________ states that alleles separate from one another during gamete formation. | Segregation
| Expected percentage of pink offspring in a cross between a red Four O'Clock plant and a white Four O'Clock plant | 50%
| Expected percentage of black and white chickens in a cross between a black chicken and a white chicken | 100%
| Inheritance pattern in which both alleles are completely expressed | Codominance
| Inheritance pattern in which there are more than two alleles for a trait | Multiple alleles
| Expected percentage of white offspring if you cross two plants that are heterozyous purple | | Inheritance pattern in which both alleles are partially expressed | Incomplete dominance
| Inheritance pattern in which there are more than two genes for a trait | Polygenic Inheritance
| Expected percentage of dominant offspring in a cross between a heterozygous dominant and a homozygous recessive parent | 50%
| Example of an codominant trait | Red and White flowered Plants |
