| A | B |
|---|
| Alleles | The two forms of gene (dominant and recessive) |
| Asexual Reproduction | One parent; produces identical offspring; Same DNA |
| DNA | The large molecule that carries the genetic code |
| Dominant Trait | The stronger of two genes expressed in a hybrid and is represented by a capital letter (B); ALWAYS shows up |
| Fertilization | Egss and sperm (sex cells) join together |
| Genetics | The study of heredity |
| Genotype | The gene combinations for a trait (BB, Bb, and bb); what the genes look like |
| Heredity | The process of passing traits from parents to offspring |
| Laws of Dominance | Developed as a result of studies with pea plants |
| Meiosis | Occurs in sex cells; called Reduction Division; Reduces the number of chromosomes in half (46-> 23) |
| Phenotype | The physical characteristics of the individual that result from the genotype |
| Punnett Square | A chart that shows the allels carried by the male and female gamests and all the possible allele combinations of the offspring |
| Recessive Trait | A trait that shows up less often in a cross and is represented by a lowercase letter (b); NOT always visible in offspring |
| Sexual Reproduction | Two parents; produces variations (different traits) in offspring; Different DNA |
| Trait | Any characteristics that can be passed down from parent to their offspring (eye color, hair color) |
