A comparison of regression interval mapping and multiple interval mapping for linked QTL

Article Abstract:

The regression interval mapping and multiple interval mapping are compared with regard to mapping linked quantitative trait loci (QTL) in inbred-line cross experiments. The results reveal that for every combination of population size and marker interval length, the power of multiple interval mapping exceeded the regression interval mapping.

Mapping of paternal-sex-ratio deletion chromosomes localizes multiple regions involved in expression and transmission

Article Abstract:

Two methods are developed to detect site-specific markers on the paternal-sex-ratio (PSR) deletion chromosomes. In order to determine the presence or absence of anonymous restriction fragments on the deletion chromosomes, assays are also developed.

Sex to some degree

Article Abstract:

Flatworms of the species Schmidtea polychroa are used for studying the evolution of sex. The flatworm proves to be a good example of an organism with a complicated reproductive mode that uses the benefits of sexual and asexual reproduction.
