3^rd chromosome nondisjunction is elevated in <i>Cap-H2</i> fertile males.

“n” refers to the number of males tested. 1Diplo-3 (het) refers to sperm that were heterozygous for the paternal male's 3rd chromosome loci. 2Diplo-3 (homo) sperm were homozygous for the paternal male's third chromosome loci. 3ND refers to a class of F1 progeny with genotypes that were “not determinable” because the flies died before they could be test crossed or the markers of the F2 progeny could not distinguish between classes. 4In the testing of the Cap-H2Z3-5163/Cap-H2Z3-5163 males, diplo-3 (het) and diplo-3 (homo) progeny were indistinguishable because they are genotypically identical for third chromosome loci.
