This problem was not helped by the non-linear response of autoradiography film to exposure time. Arrows indicate two sex-linked DNA fragments that are present in females but absent in males. Restriction enzymes with 4 bp recognition cut sites, such as Hae III, were commonly used because they cleave DNA frequently and hence typically digest the target DNA sequences close to the repeat motifs.

Sexually reproducing species have somatic cells body cellswhich are diploid [2n] having two sets of chromosomes 23 pairs in humans with one set of 23 chromosomes from each parentone set from the mother and one from the father.

Differentiation and the polymorphic nature of the Y chromosomes revealed by repetitive sequences in the dioecious plant, Rumex acetosa. An anther- and petal-specific gene SlMF1 is a multicopy gene with homologous sequences on sex chromosomes. The number of genes carried by autosomes varies from to Therefore the sex chromosomes in a female are homologous to each other.

References 1. Within two years from its description [ 7 ] and the first application of DNA fingerprinting within a legal context [ 2 ], two pioneering reports were published on mating systems in house sparrows Passer domesticus [ 8 , 9 ]. In male somatic cells of Drosophila the male-specific lethal MSL complex, which is comprised of proteins and non-coding RNAs, is targeted to the X chromosome and is necessary for transcriptional upregulation.
