| Question | Answer |
|---|---|
| Linked genes | Genes close together on the same chromosomes that don't sort independently |
| Independent assortment | Same frequency of each gamete |
| Two point test cross analysis | - 2 genes -crossed to a Homozygous recessive -Examine alleles from dihybrid to deduce recombination frequency |
| Recombination frequency calculation | r= # of recombinants/ total # of progeny x 100% |
| What is Recombination frequency? | Physical distance between 2 genes |
| When does crossing over occur at higher rates | Between genes that are further apart |
| When does crossing over occur at lower rates | Between genes that are closer together |
| What are map units called | Centimorgan |
| 1% recombination converts to what | 1 mu or 1 cM |
