Comparative chromosome painting between chicken and spectacled owl (Pulsatrix perspicillata): implications for chromosomal evolution in the Strigidae (Aves, Strigiformes)
The spectacled owl (Pulsatrix perspicillata), a species found in the Neotropical region, has 76 chromosomes, with a high number of biarmed chromosomes. In order to define homologies between Gallus gallus and Pulsatrixperspicillata (Strigiformes, Strigidae), we used chromosome painting with chicken D...
