Figure 1From: Parental origin of chromosomes influences crossover activity within the Kcnq1 transcriptionally imprinted domain of Mus musculusSchema of the mouse crosses. C57B6/J (B6) were crossed with CAST/EiJ to obtain heterozygous F1 generation. Recombination activities in the F1 generation were monitored by backcrossing these with B6 and examining their progenies.Back to article page
