The use of molecular genetic techniques is becoming increasingly widespread in analyses of hybrid zones. Yet, exactly how many molecular markers are required to provide a given degree of resolution remains an open question. We present statistical models that relate the number of markers examined to their power to discriminate between pure species, F1’s, and backcross individuals. Our models indicate that only about four or five markers are required to provide a coarse classification of…

HYBRID CLASSIFICATION: INSIGHTS FROM GENETIC MAP-BASED STUDIES OF EXPERIMENTAL HYBRIDS

This paper compares observed and expected marker numbers in 170 hybrids of known pedigree between two wild sunflower species, Helianthus annuus and H. petiolaris, and suggests that hybrids be classified either in terms of genetic relatedness or in Terms of the admixture of parental-species genes they carry.

The effects of locus number, genetic divergence, and genotyping error on the utility of dominant markers for hybrid identification

The results highlight the importance of considering the effects of each of the variables when assigning individuals to various parental and hybrid categories, and can help guide decisions regarding the number of loci employed in future hybridization studies to achieve the power and level of resolution desired.

An extensive series of simulations of amplified fragment length polymorphism (AFLP) data is performed to evaluate the prospects for hybrid identification with (possibly non-diagnostic) dominant markers.

MATHEMATICAL MODELLING AND PARENTAGE ANALYSIS OF HYBRID ZONES

The results indicate that, for a given level of migration between demes, different levels of selection have a direct impact on the cline width, with stronger natural selection causing clines to be narrower.

The Use of Fluorescent Randomly Amplified Polymorphic DNA Markers to Identify Hybrids: A Case Study Evaluating the Origins of Saugeye following the Cessation of Stocking in an Ohio Reservoir

A protocol to generate fluorescent randomly amplified polymorphic DNA (FRAPD) markers for hybridization studies, which has not previously been used for hybrid identification, is modified.

A model-based method for identifying species hybrids using multilocus genetic data.

A statistical method for identifying species hybrids using data on multiple, unlinked markers using the framework of Bayesian model-based clustering to compute the posterior probability that each individual belongs to each of the distinct hybrid classes.

Efficiency of model‐based Bayesian methods for detecting hybrid individuals under different hybridization scenarios and with different numbers of loci

The method of structure seemed to be less sensitive to the proportion of hybrids included in the sample, while newhybrids seemed to perform slightly better when individuals from both backcross and F1 hybrid classes were present inThe sample, however, separating backcrosses from purebred parental individuals requires a considerable genotyping effort, even when divergence between parental populations is high.

Increased genetic marker density reveals high levels of admixture between red deer and introduced Japanese sika in Kintyre, Scotland

This work uses 44,999 single nucleotide polymorphisms and the ADMIXTURE program to study two areas of Scotland where a panel of 22 diagnostic microsatellites previously identified introgression between native red deer and introduced Japanese sika and shows that ancestry informative markers are better than diagnostic markers because they are more evenly distributed in the genome.

Microsatellites and single nucleotide polymorphisms in avian hybrid identification : a comparative case study

The study shows that the use of various sets of markers could lead to strikingly different assignment results, hybridisation studies may have been affected by too low a resolution power of used markers, and that an appropriate set of markers is essential for successful hybrid identification.

Analysis of Hybrid Zones

Hybrid zones are narrow regions in which genetically distinct populations meet, mate, and produce hybrids, and models of parapatric speciation, and of Wright's "shifting balance," involve the formation, move­ ment, and modification of hybrid zones.

Genetic analysis of an interspecific hybrid swarm of Populus: occurrence of unidirectional introgression.

Restriction fragment length polymorphisms were used to distinguish genotypes of two species of Populus, P. fremontii ('Fremont') and P. angustifolia ('narrowleaf'), allowing identification of parental genotypes within individual trees of a hybrid swarm which exists in an overlap zone between the two species.

A NARROW HYBRID ZONE BETWEEN CLOSELY RELATED CRICKET SPECIES

This paper is the first in a series in which the nature of barriers to gene exchange between egg-overwintering, fall adult field crickets (genus Gryllus) is examined and the effects on degree of reproductive isolation of particular morphological, developmental or behavioral differences are examined.

Fisher's method of junctions is used to investigate the degree of association between selected alleles in a cline, in the limit where there is divergence between very many genes, and indicates that under weak selection the approach to equilibrium is very slow.

The hybrid-superiority hypothesis states that hybrids are more fit than parental phenotypes in some environments, and it is suggested that stable hybrid zones are often narrow because they tend to occur in ecotones which are themselves narrow.

MITOCHONDRIAL INHERITANCE PATTERNS ACROSS A COTTONWOOD HYBRID ZONE: CYTONUCLEAR DISEQUILIBRIA AND HYBRID ZONE DYNAMICS

The results demonstrate that mitochondria are uniparentally inherited in trees of known nuclear inheritance, and propose that seeds, seedlings, or trees with high proportions of heterozygous loci are at a disadvantage unless they also have the Fremont mitochondrial genotype.

Wormy mice in a hybrid zone

The findings support the view that the hybrid populations may have reduced fitness and thereby act as a genetic sink, interfering with the flow of genes between the two species, and the possibility that environmental or ecological peculiarities in the zone of hybridization make the mice more liable to infection is not supported.

Individuals analyzed from a contemporary hybrid population demonstrate multilocus genotypes that are indicative of advanced-generation hybrid individuals that demonstrate the power of the polymerase chain reaction methodology for the rapid identification of random and specific genetic markers for testing evolutionary genetic hypotheses.

Gene exchange in a ground cricket hybrid zone.

The discovery of several random amplification of polymorphic DNA (RAPD) markers that distinguish the two species of ground crickets and the congruence of RAPD markers and protein markers with regard to the identification of hybrids in mixed populations is assessed.
