A genetic map of quantitative trait loci for body weight in the mouse

Article Abstract:

The frequency changes of microsatellite marker alleles in inbred mice were analyzed to determine genetic factors which influence body weight. Several peaks of frequency changes were observed in several regions of the genome, suggesting that single genes exhibit moderate effects on body weight. In addition, 11 quantitative trait loci (QTL) were identified using a maximum likelihood method. However, additional tests to identify other QTLs in regions where larger changes in marker allele frequency proved inconclusive.

Test of a candidate gene-quantitative trait locus association applied to fatness in mice

Article Abstract:

Five genes regarded as strong candidates for determining obesity were tested for association with quantitative variation of fatness in mice. No significant results were obtained for overall body fat content from a randomization test. The test was based on empirical distribution of LOD scores obtained from a genetic scan for quantitative trait loci applied to statistics on body fat context and male gonadal fatpad weight.

Major quantitative trait loci affecting honey bee foraging behavior

Article Abstract:

A study was conducted to identify the two genomic regions affecting the amount of pollen stored in honey bee colonies and to determine whether foragers will collect pollen or nectar. The amount of pollen stored in combs of honey bee colonies were collected. Colony-level trait were examined by random amplified polymorphic DNA markers. The results are presented and discussed.
