Packet 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 (15[1])of this phenomenon. (15[2])Since P of AB does not necessarily equal P of A times P of B, (-5[1])this phenomenon (-5[1])causes a “disequilibrium.” (-5[1])Namesake “maps” (15[1])of this phenomenon are based on (*) recombination frequencies (-5[1])obtained from (10[1])two point (10[1])test (10[1])crosses. (-5[2])By studying the inheritance of eye (-5[1])and body color on Drosophila, (-5[1])Thomas Hunt (-5[1])Morgan proved the occurrence of this phenomenon that violates Mendel’s law (10[1]-5[1])of independent (-5[2])assortment. For 10 points, (10[1]-5[2])name this phenomenon (-5[1])where two genes (-5[1])close on the same chromosome (10[1]-5[1])are inherited together. ■END■ (10[6]0[28])
