“…Variation in hemoglobin proteins, previously described by Foreman (1966) and Price and Kennedy (1980), also was observed in this study. We found the familiar two-and threeband patterns, plus different three-band patterns and patterns with more than three bands.…”

“…The basic pattern of phenetic similarities followed the pattern described above for the ALB locus and did not follow the distribution of named subspecies. DISCUSSION Genetically, P. gossypinus is a variable species-more than expected from previous studies of Price and Kennedy (1980) and Robbins et al (1985) and somewhat more variable than observed by Boone et al (1993). The percentage of variable loci and number of alleles per locus were increased from that previously known, although mean heterozygosity decreased.…”

“…Price and Kennedy (1980) found few variable loci (3 of 14), little average individual heterozygosity (2.9%), and no geographic pattern in the allozyme variation. Examining more loci, individuals, and locations, Robbins et al (1985) found a larger number of variable loci (8 of 25) and higher average individual heterozygosity (4.7%).…”

We examined allozyme variation at 40 presumptive gene loci in 1,904 cotton mice (Peromyscus gossypinus) from 62 locations throughout the range of the species. This species was highly variable: 92.7 percent of loci were polymorphic, observed heterozygosity per population ranged from 0.023 to 0.123 and averaged 0.088, and number of alleles per polymorphic locus averaged 5.6. The least variable populations were from the western part of the range, and the most variable were from the southeastern part. Virtually every population contained unique or rare alleles. Distribution of allozyme variation generally reflected geographic proximity rather than existing subspecies boundaries, with major differences between western, northeastern, southeastern, and insular populations. The most divergent populations were from Georgia and Florida sea islands, but drift alone could not explain this observation, because the largest number of unique alleles per population also occurred in these populations.

“…These species show some level of sexual isolation: when allopatric or sympatric P. leucopus and P. gossypinus are placed in large arenas, both species mate with conspecifics (Bradshaw , ). Although assortative mating in laboratory studies is potentially strong, there is mixed evidence as to whether it is strong enough to prevent hybridization in wild sympatric populations (Howell ; Dice ; McCarley ; Price and Kennedy ; Robbins et al. ; Barko and Feldhamer ).…”

Sexual imprinting and speciation between two Peromyscus species

Sexual isolation, a reproductive barrier, can prevent interbreeding between diverging populations or species. Sexual isolation can have a clear genetic basis; however, it may also result from learned mate preferences that form via sexual imprinting. Here, we demonstrate that two sympatric species of mice-the white-footed mouse (Peromyscus leucopus) and its sister species, the cotton mouse (P. gossypinus)-hybridize only rarely in the wild despite co-occurrence in the same habitat and lack of any measurable intrinsic postzygotic barriers in laboratory crosses. We present evidence that strong conspecific mating preferences in each species result in significant sexual isolation. We find that these preferences are learned in at least one species: P. gossypinus sexually imprints on its parents, but in P. leucopus, additional factors influence mating preferences. Our study demonstrates that sexual imprinting contributes to reproductive isolation that reduces hybridization between otherwise interfertile species, supporting the role for learning in mammalian speciation.
