Exploring the molecular differentiation of sex chromosomes in Anastrepha fraterculus sp. 1 using comparative genomic hybridization (CGH) por Giardini, Maria Cecilia, Milla, Fabian Horacio, Conte, Claudia Alejandra, Lanzavecchia, Silvia Beatriz, Nieves, Mariela

“…Our aim was to explore the molecular composition of the sex chromosomes identified in the laboratory strain Af-Y-short due to it possesses the most frequent sex chromosomes variants, and the smallest Y chromosome found in wild populations and laboratory colonies of A. fraterculus sp. 1. Methods and results: Whole Comparative Genomic Hybridization (W-CGH) was applied to the Af-Y-short laboratory strain to identify potential differences in the size and composition of highly repetitive DNA blocks between individuals, morphs or sexes. …”
