Specific recognition and differential affinity of meiotic X-Y pairing sites in Lucilia cuprina males (Diptera: Calliphoridae)

Meiotic pairing of X and Y chromosomes in male Lucilia cuprina was studied by cytological observation of normal, rearranged and deficient sex chromosome karyotypes in spermatogenesis. Two X - Y pairing regions located distally in each arm of the X and Y chromosomes were defined. Contrasting with fin...

Beschreibung
Zusammenfassung:	Meiotic pairing of X and Y chromosomes in male Lucilia cuprina was studied by cytological observation of normal, rearranged and deficient sex chromosome karyotypes in spermatogenesis. Two X - Y pairing regions located distally in each arm of the X and Y chromosomes were defined. Contrasting with findings in Drosophila melanogaster , these pairing regions show specific recognition of their partners.
