Divergent selection for four-week body weight in Japanese quail (Coturnix coturnix japonica): response to selection and realized heritability
The Japanese quail has been utilized as a research species in establishing the genetic relationships that may also be present in other species. Divergent phenotypic selection for 4-wk BW was conducted for three generations in high (HW) and low (LW) lines. Within each line, 50 females and 25 males were selected among 600 birds, based on 4-wk BW. Mean BW at 4 wk of age in the base generation was ...

and genetical behavior of this form is not incompatible with the segmental interchange theory of circle formation in Oenothera. Summary.-It is impossible for the alethal complex of a primary halfmutant derived from Lamarckiana by a single segmental interchange to give the same chromosome configuration with both complexes of the parent species. Nevertheless, a further segmental interchange betwe...

متن کاملLong-term divergent selection for eight-week body weight in white Plymouth rock chickens.
This paper provides an overview of results from a long-term (38 generations) selection experiment. Lines were developed from individual phenotypic selection for high or low body weight at 8 wk of age. Included are data for the selected lines, sublines in which selection was relaxed, crosses of the selected lines, and sublines in which the sex-linked dw gene was introduced. Periodically (and in ...
متن کاملLong-term Divergent Selection for 8-week Body Weight in Chickens – a Review of Experiments
In order to study the effects of long-term selection on genetic parameters, the effect of selection on selected and correlated traits and to develop lines for various physiological, biochemical and molecular genetic studies a comprehensive selection study for body weight in chickens has been conducted at the Biotechnical Faculty of University in Ljubljana. Long-term divergent selection in chick...
