The realisation that heterozygosity can be heritable has recently generated some elegant research. However, none of this work has discussed the fact that when heterozygote advantage occurs, heterozygosity can be heritable, yet allele frequencies remain at equilibrium and do not evolve with time. From a quantitative genetic perspective this means the character is heritable, is under selection, y...

this study was carried out to investigate the direct and indirect responses to selection for four-week body weight (4 week body (wk bw)) and four-week breast weight (4 week breast weight (wk brw)) and to determine the genetic contribution of reminder founders to the last generation. a total number of 351 birds were equally allocated to three lines, including two selected lines (s1 and s2 for bw...
