Hybridization is an important evolutionary mechanism in plants and has been increasingly documented in animals. Difficulty in reconstruction of reticulate evolution, however, has been a longstanding ...
Similar to conventional comparative genomic hybridization (CGH), but during hybridization, cloned chromosomal DNA fragments (about 200 kb in size) replace the metaphase chromosomes. This method offers ...
A molecular cytogenetic method of screening cells for DNA gains and losses at a chromosomal level. Differentially labelled test and reference DNA are hybridized simultaneously to metaphase chromosomes ...
