Allozyme Variation in the Cotton Mouse (Peromyscus gossypinus)

Studies of mitochondrial DNA, allozyme and morphometric variation in a house mouse hybrid zone.

An unusual chromosomal hybrid zone of the house mouse, Mus musculus domesticus, exists in Upper Valtellina, Northern Italy, consisting of four Robertsonian (Rb) races and the standard (all-acrocentric, or 2n = 40) race, all hybridizing freely within 10 km2. The hybrid zone in Valtellina provides an excellent opportunity to study the role of Rb fusions in reproductive isolation and speciation. T...

Morphologic Variation in the Osteopetrotic Op/Op Mouse Skeleton

SUMMARY This study is designed to confirm the changes of various bones in the osteopetrotic op/op mouse. The female adult mouse were sonicated in papain solution. After the complete treatment, the bones (Skull, Mandible, Scapula, Humerus, Radius, Ulna, Hip, Femure, Tibia, Atlas, Axis and 5th Lumbar vertebra) were measured three dimensionally using of high quality scale and low power binocular ...

The evolution of social and reproductive monogamy in Peromyscus, evidence from Peromyscus californicus (the California Mouse)

Allozyme variation in the endangered insular endemic Castilleja grisea.

BACKGROUND AND AIMS Genetic diversity in Castilleja grisea, an endangered, perennial herb endemic to San Clemente Island, California was investigated. Subsequent to the elimination of goats from the island in 1992, many populations of C. grisea have reappeared and have been increasing in size. METHODS Nineteen populations were surveyed for their genotype at 19 allozyme loci. KEY RESULTS At ...
