Question | Answer |
Two forms of a gene (dominant or recessive) | Alleles |
Piece of DNA that codes of a trait, basic physical and functional unit of heredity | Gene |
Any characteristic that can be passed from parent to offspring | Trait |
Traits that must be passed through DNA and cannot be changed | Inherited traits |
Learned behaviors that are not passed through DNA | Acquired traits |
Passing of traits from parent to offspring | Heredity |
Study of heredity | Genetics |
Stronger of two possible alleles, represented by a capital letter | Dominant |
Gene that shows up less often in a cross, lowercase letter | Recessive |
Gene combination for a trait, described by letters only (ex. BB, Bb, or bb) | Genotype |
Physical feature resulting from a genotype (ex. brown eyes) | Phenotype |
hybrid, both alleles are different | Heterozygous |
pure bred, both alleles are the same | Homozygous |
diagram used to predict probabilities of different offspring | Punnett Square |
Scientist that first studied genetics in detail | Gregor Mendel |
a synonym for homozygous | Pure Bred |
a synonym for heterozygous | Hybrid |
has a trait but it is not showing | Carrier |
both phenotypes will show in a hybrid (ex. red and white spotted flowers) | codominance |
both phenotypes will mix to produce a unique phenotype for hybrids (ex. pink flowers from white and red flowers) | incomplete dominance |
