Phylogram demonstrating the relationships among various mouse mammary tumor env-pol sequence detected in either mice (MMTV) or human (HMTV) samples. Sequences labeled in the 49,000’s are described herein; all others are from the literature. The mouse strains from which certain sequences were obtained are as indicated. Sequences of human endogenous HERV-K family of retroviruses were used as an outgroup. The symbol (*) indicates branches where the bootstrap value was above 90%. The bar at bottom indicates a distance of 10%
