Hirosaki Hairless
Hirosaki Hairless, hhr/hhr
Two copies of the recessive Hirosaki Hairless
Chromosome: Unknown
RVG description:
HHRs are nearly bare with some sparse and short hairs, and also distinguishable from normal rats by characteristics bent whiskers. In addition to hair loss, female HHRs show involution of the mammary gland at an early stage of lactation, and most newborn rats die within a week because of less feeding.
The HHR exhibited sparse hair cover over the whole body, and their twisted hairs with a single bend were shorter than the straight hairs of SDR. The HHR also showed twisted vibrissae.
