Round 4: Tossup 18
In 1905 Bateson and Punnett set forth the “coupling” and "repulsion" phases of this phenomenon. An LOD score of three or higher is an indication of this phenomenon. Since P of AB does not necessarily equal P of A times P of B, this phenomenon causes a “disequilibrium.” Namesake “maps” of this phenomenon are based on (*) recombination frequencies obtained from two point test crosses. By studying the inheritance of eye and body color on Drosophila, Thomas Hunt Morgan proved the occurrence of this phenomenon that violates Mendel’s law of independent assortment. For 10 points, name this phenomenon where two genes close on the same chromosome are inherited together. ■END■
ANSWER: genetic linkage [accept coupling linkage, repulsion linkage, linkage disequilibrium, or linkage maps]
