F1 females from a cross of AABBCC to aabbcc were backcrossed to aabbcc males. IN the progeny of this cross there were 150 AaBbCc, 145 aabbcc, 55aabbCc, 52 AaBbcc, 31 aaBbcc, 29 AabbCc, 5 Aabbcc and 3 aaBbCc.

Is there evidence of interference? What is the coefficient of coincidence?

#### Solution Preview

In the given question we have to calculate the expected number of double recombinants. The concept is that given specific recombination rates in two adjacent chromosomal intervals, the rate of double-crossovers in this region should be equal to the product ...

#### Solution Summary

Coefficient of coincidence and interference can be calculated with the help of the number of progeny obtained from a back cross or test cross.
