For example, Aquadro and Patton (1980) demonstrated that species-specific differences in salivary amylase electromorph
phenotypes could be used to unambiguously distinguish between morphologically similar Peromyscus leucopus and P.
Interpreting stained electromorph
bands on a gel requires a thorough understanding of the genetic basis of allelic variation for each enzyme (reviewed by Richardson et al.
B in our study), (2) differential resolution of alleles may have resulted from our use of different support media or buffers (i.e., electromorph
splittings; see Richardson et al., 1986), (3) one or more of these three species may exhibit geographic population genetic differences (i.e., different populations have different genotypes) due to limited gene flow or differential selection, or (4) one or more of these species may be represented by more than one morphologically identical yet reproductively isolated species (i.e., cryptic species), essentially meaning that Wright and White (1992) did not assay all Pteronarcys species.
The fast electromorph
of AAT was only observed in the Duke Forest populations, whereas alleles of GPI and EST were widespread and polymorphic within most populations.
At these loci, the plant samples from each population were homozygous for a single electromorph
are designated by relative anodal migration speed (f = fast, i = intermediate, s = slow).
Upon completion of the initial survey, samples of each variant electromorph
were rerun in lineup gels to assign relative mobility and establish the veracity of the initial interpretation.
cornutus exhibits this fast electromorph
and, more commonly, a unique slow allele (Dowling and Moore 1984).
A slow electromorph
presumably representing GPI-[A.sup.c] has been reported in only 8 of 31 samples of C.
Allozyme loci were scored by examining electromorph
mobility patterns relative to the common electromorph
frequency shifts between populations and across hybrid zones exist for some loci, fixed differences are rare, and few intra-specific phylogenetic inferences may be made.
We treated each and every electromorph
as a binary (present/ absent) character.
