Sex differences in gait utilization and energy metabolism during terrestrial locomotion in two varieties of chicken (gallus gallus domesticus) selected for different body sizeIn leghorn chickens (Gallus gallus domesticus) of standard breed (large) and bantam (small) varieties, artificial selection has led to females being permanently gravid and sexual selection has led to male-biased size dimorphism....

The use of esterase polymorphism for analysis of the genetic diversity and structure of stevia (stevia rebaudiana bert. bertoni) populations ... The esterase analysis employed in this study showed that the artificial selection of plant samples with specific uniform characteristics, such increased height and precocious flowering, may lead to the fixation of alleles and α/β-esterase...

Construction of a high-density linkage map and mapping of sex determination and growth-related loci in the mandarin fish (siniperca chuatsi)... However, the lack of selective breeding of mandarin fish in previous decades has resulted in a decline in the growth rate of pond-cultured fish, a shortened period of sexual maturity, and reduced ...
