MCQ
The map distance between genes $A$ and $B$ is $3$ units, between $B$ and $C$ $10$ units and between $C$ and $A$ $7$ units. The order of the genes in a linkage map constructed on the above data would perhaps be
  • A
    $A, B, C$
  • B
    $A, C, B$
  • C
    $B, C, A$
  • $B, A, C$

Answer

Correct option: D.
$B, A, C$
d
(d) From the recombination frequencies between different genes $A, B$ and $C$, it is clear that distance between $A$ and $B$ genes is $3$ units, between $B$ and $C$ $10$ units and $C$ and $A$ $7$ units. Hence linear order of genes on chromosomes is :
