The value of interference is 43%.
The AbC/ABC and aBc/ABC are double cross over progenies. Because AbC and aBc are produced from heterozygous parent by double cross over.
aBc gametes are produced from aBc/aBc parent.
Observed numbers of double cross overs are: 4+2= 6
Expected numbers of double cross overs are:
Genetic distance between (A-B/100)×(B-C/100) ×Total
=(7/100) ×(30/100) ×500
= 0.07 ×0.30 ×500
= 10.5
Coefficient of coincidence= Observed double cross over /Expected double cross over
= 6/10.5
= 0.57142
Interference= 1-coefficient of coincidence
= 1-0.57
=0.43
Interference in terms of percentage is: 0.43×100
=43%
Therefore, the 43% of interference occurs due to inhibition of cross over at another region due to crossing over at adjacent region.
