| hybrid | the offspring of a cross between individuals who contrasting traits |
| generation | the entire group of offspring produced by a given group of parents |
| pedigree | a diagram that shows the occurances of a genetic trait in several generations of a family |
| genettic disorder | an inherited disease or disorder that is caused by a chromosomal defect or mutation |
| codominance | a condition in which both alleles for an gene are fully expressed |
| incomplete dominance | an offspring has a phenotype that is intermediate between the traits of both parents |
| law of independent assortment | states that the genes separate independently of one another in meiosis. |
| punnett ssquare | a graphic use dto predict the results of an genetic cross |
| dominant | describes an allele taht is fully expressed |
| recessive | desribes an allele that is expressed only when no dominant allele is present |
| phenotype | organism's appearance that results from the organism's genotype and environment. |
| genotype | the entire genetic makeup of an organism; also the combination of genes for one or more specific traits |
