title: [A simple method to correct genetic distance between linked genes and a correction of calculating data in tetrad analysis in Neurospora crassa].
abstract: The present paper is dealing with a simple method to correct the distance of linked genes in tetrad analysis in Neurospora crassa. It is suggested that the data of 4-thread double crossing over should be added in two single crossing over respectively in centromere maping when calculating crossover value of the two genes locating across the centromere.
