Vedclass · Answer

(C) The percentage of recombination is directly proportional to the distance between genes on a chromosome (where $1\%$ recombination = $1$ map unit or centimorgan).Given:Recombination frequency between $A$ and $B = 9\%$Recombination frequency between $A$ and $C = 17\%$Recombination frequency between $B$ and $C = 26\%$Since the distance between $B$ and $C$ $(26\%)$ is the sum of the distances between $A$ and $B$ $(9\%)$ and $A$ and $C$ $(17\%)$,i.e.,$9 + 17 = 26$,it implies that gene $A$ lies between genes $B$ and $C$.Therefore,the linear arrangement of the genes is $B-A-C$ or $C-A-B$.

The percentage of recombination between genes $A$ and $B$ is $9\%$,between $A$ and $C$ is $17\%$,and between $B$ and $C$ is $26\%$. What is the correct arrangement of these genes on the chromosome?
