Abstract excerpt
Provirus ev21 was found in both K- and k(+)-feathering Rhode Island Red commercial layers. Probe EV21-int revealed the presence of two distinct but similar regions, US (unoccupied site) and OS (occupied site). Restriction analysis showed that these regions had at least 19 kb structural homology but were distinguishable by ev21 proviral sequences, OS, and possibly three polymorphics US. The loci OS and US were...
