| Question | Answer |

| what is genetic recombination? | the production of offspring with combinations of traits that differ from those found in either P generation parent |
| what are parental types? | offspring with a phenotype that matches one of the true breeding parental phenotypes |
| what are recombinant types? | offspring whose phenotype differs from that of the true breeding p generation parents |
| what is crossing over? | reciprocal exchange of genetic material between nonsister chromatids during prophase 1 of meiosis |
| what is a genetic map? | ordered list of genetic loci along a chromosome |
| what is a linkage map? | a genetic map based on the frequencies of recombination between markers during crossing over of homologous chromosomes |
| what are map units? | unit of measurement of the distance between genes |
