Question | Answer |
Heredity | The passing of traits from parent to offspring |
What is the structure of DNA? | Double Helix |
Heterozygous | A genotype with two different alleles, one dominant and one recessive |
Homozygous | A genotype with the of the same alleles |
Homozygous Dominant | A genotype with two dominant alleles |
Homozygous Recessive | A genotype with two recessive alleles |
Genotype | An organism's allele combination |
Phenotype | An organism's physical appearance |
Gene | The genetic information passed from parent to offspring |
Allele | Different versions of a gene: dominant or recessive |
Gregor Mendel | The scientist that is credited with developing the theory of modern genetics |
Chromosome | Threadlike structures that contain an organism's DNA |
Trait | A physical feature that an organism inherits from its parent |
Dominant Trait | A trait that is always observed when the allele is present |
Recessive Trait | A trait that is only observed when there are two recessive alleles inherited |
What are the three parts of cell theory? | 1. All living things are made of cells 2. Cells are the basic unit of structure and function in living things 3. Cells come from other cells |
What are the three reasons that cells divide? | Cells divide for growth, repair, and reproduction |
What are the two types of cell division? | Mitosis and Meiosis |
Mitosis | Cell division that creates body cells for growth, repair, and asexual reproduction |
Meiosis | Cell division that creates sex cells for sexual reproduction |
Hybrid is a synonym for... | Heterozygous |
Purebred is a synonym for... | Homozygous |
Co-dominance | A trait in which two alleles demonstrate the dominant trait |
Example of co-dominance in humans | blood type |
What are the four human blood types? | Type A, Type B, Type AB, Type O |
Which alleles for blood type are codominant? | A and B |
Which allele for blood type is recessive? | O |
What is incomplete dominance? | A trait in which neither allele demonstrates the dominant trait, creating a third phenotype that is a blend of the two (example: A red flower and a white flower can create a pink flower). |
