Efficient transmission of y-MCR element. A) Mendelian versus MCR inheritance of a yellow (y) allele. B) Structure of the y-MCR construct and its insertion into the genome at the yellow locus on the X chromosome. C) Summary of results of 8 crosses between F1 y- heterozygous flies and y+ flies (2 male MCR and 6 female MCR crosses) yielding a total of 527 F2 progeny. The MCR transmission rate in the experiments was 97%, which translates into a 95% rate of the MCR allele converting the opposite allele in the germline (conversion % = 2(X – 0.5N)/N where N = total number of flies and X = number of y flies with a y- phenotype or y mosaic phenotype).
