Meiotic Recombination in the Giraffe (G. reticulata).

abstract：:Chromosome homologies in reptiles have been investigated extensively by gene mapping and chromosome painting. Relative chromosome size can be estimated roughly from conventional karyotypes, but chromosome GC content cannot be evaluated by any of these approaches. However, GC content can be obtained by whole-genome seq...
