| Who developed simple set of rules/laws accuratly predicted patters of heredity? | Mendel |
| How did Mendel explain natural phenomena? | used mathmatics |
| What did he use to create the P generation of purebreads? | self pollination |
| Punnet Square | used to determine the outcome of the cross |
| Homozygous | 2 alleles are the same |
| Heterzygous | 2 alleles are different |
| An individual recieves how many alleles from their parents? | 1/2 from each parent |
| Genotype | individuals set of alleles |
| Phenotype | physical expression of the alleles |
| Law of Dominance and Recessiveness | individual possess both a dominant and recessiveallele for the same trait- - > dominant allele is expressed in the phenotype |
| Law of Segregation | memebers of each pair of alleles separate when gametes form |
| Law of Independent Assortment | pairs of alleles independently of one another during gamete formation |
| incomplete dominance | traits is intermediate between 2 parents |
| codominance | condition in which both alleles for a gene are expressed when present |
| multiple alleles | having more than 2 alleles for a genetic trait |
| continous variation | genetic phenomenon in which a trait is controlled by several genes and therefore exhibits a variety of phenotypes |
| enviromental influences | phenotype often depends on conditions in the enviroment |
| mutations | change in DNA of a gene or chromosome |
| genetic disorder | mutated genes |
| sickle cell anemia | condition cause by mutated allele that prodcues a defective form of the protein hemoglobin |
| sex-linked trait | trait that is determined by a gene found on the X chromosome |
| hemophilia | genetic disorder that impairs the blood's ability to clot and cause excessive bleeding |
| pedigree | family history of traits recorded over generation indentifying which relatives exhibit a trait |
| phenylketonuria (PKU) | genetic disorder in which an individual lacks an enzyme that converts the amino acid phenylalanine into the amino acid tyrosine |
