Fig. 2From: The impact of genetic background and cell lineage on the level and pattern of gene expression in position effect variegationPEV phenotype of the progeny from the cross between the A1 and D1 inbred lines. a PEV levels in the adult progeny. Each data point represents a sample of five flies from a population of the indicated genotype (see “Materials and methods”). Results observed were essentially the same from crosses in either direction (females listed first). b The PEV pattern in the adult fly eye from randomly selected F1 progeny of a cross between the A1 and D1 inbred lines in the indicated direction. c Selected images of the PEV pattern in the F2 population representative of the diversity in pigmentation levels observedBack to article page
