A situation in which the coefficient of coincidence is greater than 1.0 would indicate that: A. no double crossovers were found in the progeny of a testcross, even though some were expected based on probability. B. there were more double crossovers in the progeny than would be expected based on probability. C. the genes involved were actually assorting independently. D. the interference is high and one crossover suppresses the occurrence of a second one. E. double crossovers were found in the progeny of a testcross, but there were fewer of them than would be expected based on probability.

B. there were more double crossovers in the progeny than would be expected based on probability

Explanation:

Crossing over or recombination can be defined as the exchange of genetic material between homologous chromosomes during meiosis. Moreover, the coefficient of coincidence is the number of double recombinants found in the progeny. The coefficient of coincidence can be estimated by the following equation:  

Coefficient of coincidence  (COC) = ADRF / EDRF

where ADRF = Actual Double Recombinant Frequency

and  EDRF = Expected Double Recombinant Frequency

In the case above described, ADFR is higher than EDRF, and therefore COC will be higher than 1.
