HE fate of genes and chromosomes following interspecific gene transfer Tdeserves detailed study. Genes of one species often can be introduced into another without evident changes of their action and with little effect upon their stability. ANDERSON'S (1949) widely known work on introgression after interspecific hybridization could not have been successful had he been dealing with unstable genet...
Hybrids between species are often characterized by novel gene-expression patterns. A recent study on allele-specific gene expression in hybrids between species of Drosophila revealed cases in which cis- and trans-regulatory elements within species had coevolved in such a way that changes in cis-regulatory elements are compensated by changes in trans-regulatory elements. We hypothesized that suc...
This study was aimed to differentiate parental genomes, examining intergenomic composition, and mapping mitotic metaphase chromosomes by localizing 18S rDNA probes in seven interspecific hybrid progenies that originated from Lilium longiflorum. Since single method of situ hybridization has been widely used lily breeding, while this study, flow cytometry conjunction with genomic fluorescent dete...
