Vedclass · Answer

(A) The distance between genes is proportional to the percentage of crossing over. Given:$1$. Crossing over between $a$ and $b = 20\%$$2$. Crossing over between $b$ and $c = 28\%$$3$. Crossing over between $a$ and $c = 8\%$Since the distance between $b$ and $c$ $(28\%)$ is the sum of the distances between $b$ and $a$ $(20\%)$ and $a$ and $c$ $(8\%)$,gene $a$ must be located between $b$ and $c$.Therefore,the sequence of genes on the chromosome is $b-a-c$.

There are three genes $a, b, c$. The percentage of crossing over between $a$ and $b$ is $20\%$,between $b$ and $c$ is $28\%$,and between $a$ and $c$ is $8\%$. What is the sequence of genes on the chromosome?
