Phylogeny and evolutionary analysis of goat breeds in Jordan based on DNA sequencing.

Phylogeny and evolutionary analyses were performed for Jordan goat breeds based on DNA sequencing. DNA segment of 0.5-kb from sixteen goat individuals of four breeds was sequenced.

Integrating genetic linkage maps with pachytene chromosome structure in maize.

Genetic linkage maps reveal the order of markers based on the frequency of recombination between markers during meiosis. Because the rate of recombination varies along chromosomes, it has been difficult to relate linkage maps to chromosome structure. Here we use cytological maps of crossing over based on recombination nodules (RNs) to predict the physical position of genetic markers on each of the 10 chromosomes of maize.
