| genetics | study of heredity |
| genes | segment of DNA on chromosome that codes for specific trait |
| phenotype | an organisms physical charactersitics |
| genotype | organisms genetic makeup or allele combination |
| chromosomes | carries genetic information that conterols inherited characteristics |
| traits | ccharactersistic that an organism can pass on to it's offspring |
| genetic engineering | transfer of DNA of one organism to another to produce desired traits |
| dominant allele | trait always shows up in in organism when trait is present |
| recessive allele | an allele that is masked when the dominant allele is present |
| hybrid | an organism has two different alleles for a trait |
| Punnett square | chart that shows possible combinations of alleles that can result from a genetic cross |
| father of heredity | gregor mendel first person to demonstrate that principles of probability can be used to predict probability of gentic outcome |
| meiosis | Process in sex cellswhere number of chromosomes is reduced by half |
| allele | different forms of a gene |
| probability | likelihood that an event will occur |
