Tissue culture increases meiotic pairing of regenerants from barley x Canada wild rye hybrids
Article Abstract:
Research into the impact of tissue culture and cytoplasm on meiotic pairing of Canada wild rye (CWR) x barley hybrids and regenerants has produced hybrids and regenerants that phenotypically all resemble the CWR parent. There were morphological differences in leaf width, height, number of spikelets, plant vigour and number of spikes between regenerants, but this was not connected with chromosome number. There was significantly increased pairing in regenerants derived from hybrids between barley and CWR, showing that tissue culture can be used to boost the chance of genetic recombination.

Use of cellular oncogene probes to identify Morone hybrids
Article Abstract:
A study was done to evaluate the capacity of cellular oncogene probes to identify F1 hybrids and lineage of the Morone species. Fixed genotypic differences were found among the four species of Morone and the heritability of the nuclear DNA genotypes was discovered to be viable for all F1 Morone hybrid species. These results validate the Mendelian inheritance of the nuclear DNA fragments in Morone fish species. Furthermore, it was shown that cellular oncogene probes can act as markers in identifying F1 hybrids.

Cytonuclear disequilibrium in chrysochus hybrids is not due to patterns of mate choice
Article Abstract:
The patterns of cytonuclear disequilibrium in chrysochus hybrids between nuclear allozyme loci and partial mitochondrial COI and COII restriction fragment length polymorphism patterns were investigated within a population of hybridizing chrysomelids beetles. The degree to which genotype frequencies of F1 hybrids were consistent with patterns of mate choice or endosymbiont infection is assessed.
