Genetic correlates of phenotypic variation in the pocket gopher (Thomomys bottae) in California

Article Abstract:

The genetic variation in the populations of the pocket gopher, Thomomys bottae, in California are positively related to the morphological variations. This is due to the correlation between the level of additive genetic variations with the heterozygosity in the populations. The genetic-phenetic variation correlation (GPVC) in males is highest when characters are correlated with the body size. In females highest GPVC is poorly correlated with the body size. The genetic variation can explains 50% of the observed phenotypic variation in females and 80% of that in males.

Inherited Occipital Hypoplasia/Syringomyelia in the Cavalier King Charles Spaniel: Experiences in Setting Up a Worldwide DNA Collection

Article Abstract:

Criteria for a successful database include support from pet owners and pedigree breed clubs, commitments from individuals who are able to devote time to communicating with clubs and breeders and to coordinate sample collection, and means for easily collecting and storing the obtained phenotypic and genotypic information.

Multiple paternity and breeding system in the gopher tortoise, Gopherus polyphemus

Article Abstract:

The mating system and reproductive behaviors of a population of gopher tortoises (Gopherus polyphemus) in central Florida are examined. Results found that gopher tortoises exhibited a promiscuous mating system with larger males fertilizing the majority of clutches.
