Genetic studies in poultry. I. Inheritance of leg-feathering

Abstract: 288Referate.H~afiger als auf Atavismus beruht die Polydaktylie beim Pferde auf einer V e r d o p p e l u n g des Furies: an der Medialseite des eigentlichen Furies (des ,ordin~ren" Furies nach der Ausdrucksweise des Verf.) ist ein anderer Fut3 entstanden, der ein Spiegelbild des ersteren darstellt. Bald betrifft die Verdoppelung nut die Zehe alleinl bald erstreckt sie sich bis in den Carpus resp. Tarsus hinauf; bei ein und demselben Tier kann die Abnormitat an den versehiedenen Extremitaten in verschiedenem Ma… Show more

“…The higher δ-aminolevulinic acid synthase activity in brown-egg laying hens compared to white-egg laying hens suggests that the trait is purely controlled by genes (Schwartz et al, 1980). Brown eggshell color is due to a dominant gene that is epistatic to the recessive white shell color gene (Punnett and Bailey, 1920); however, the phenotypic heritability calculations for dams (s 2 = 0.9135) for eggshell color in brown-shelled eggs showed some dominance over sire (s 2 = 0.3035) (Blow et al, 1950). Similarly, in measuring the heritability estimates of sire and dams for shell color in a Light Sussex flock, the dam heritability was higher than the sire, indicating the existence of a dominance effect (Hunton, 1962).…”

“…Feathered leg is an attractive trait in fancy chicken breeding, with leg feathering in such breeds ranging from sparse like in Langshan chickens to extensive like in the Cochin breed ( Somes 1992 ). Poultry geneticists have studied the inheritance of feathered legs since the beginning of the last century ( Punnett and Bailey 1918 ; Dunn and Jull 1927 ; Warren 1933 ). Somes (1992) , based on the results of test mating, provided genetic evidence for the presence of two independent dominant mutations, denoted Pti-1 and Pti-2 , causing feathered legs in domestic chicken.…”

“…Though broodiness is a natural instinct, there are several factors that might affect intensity of broodiness in avian species. a) Breed or strain: Broodiness is a heritable trait in poultry [8]. There are hundreds of chicken breeds and varieties in the world having specific broodiness characters.…”
