Question

If the distance between the genes A,B,C on the chromosomes is as
follows Prepare a genetic map assigning the correct order of genes
Which of the genes pairs will show maximum frequency of crossing
over ?A=5cm,B-C=3cm,A-C=2cm

Mushtaq Ahmed · Accepted Answer

Given,
A= 5 cm, it should be actually AB= 5 cm
AC= 2cm
BC= 3 cm
The genetic map of the genes A, B and C can be depicted as
under:

The AB pair of genes will shown maximum 
frequency of crossing over as the frequency of crossing over
increases with the increase in distance This is due to the reason
that genes which are closely located are strongly linked and thus
show less crossing over

If the distance between the genes A,B,C on the chromosomes is as follows.Prepare a genetic map assigning the correct order of genes.Which of the genes pairs will show maximum frequency of crossing over ?A=5cm,B-C=3cm,A-C=2cm.
