    Beta-Globulin Polymorphism of Karakaş, Lambs in Van Farms
    (Scientific and Technical Research Council of Turkey, 1996) Baş, S.; Ülker, H.; Vanli, Y.; Karaca, O.
    The frequencies for genes of Tf A, Tf B, Tf D, Tf M, Tf E ve Tf S which were typed by polyacrilamyde gel electrophoresis were 0.219, 0.278. 0.199, 0.241, 0.037 and 0.026, respectively. 4 homozygous (Tf AA. Tf BB, Tf DD ve Tf MM) and 15 heterozygous (Tf AB, Tf AD. Tf AM. Tf AE. TF AS. Tf BD. Tf BM. Tf BE. Tf BS. Tf DE, Tf DS. Tf ME. Tf MS ve Tf ES) were determined in the flocks. The diferrences between emprical and theoretical distributions for beta-globulin phenotypes were highly significant (P<.01 ). Significant departure from Hardy-Weinberg equilibrium was probably due to the facts that the flocks were closed to gene flow.

    The Phenotypic and Genetic Parameters of Egg Yield and Some Egg Characteristics in Pekin Duck
    (Scientific and Technical Research Council of Turkey, 1997) Karaca, O.; Altin, T.
    This research was conducted to estimate the phenotypic and genetic parameters of egg production traits in Pekin duck. The age (year) of duck were used to adjust observed egg yield, egg weight, egg length, egg width and shape index. Genetic parameters based on half-sib and full-sib were generally medium-high. Mainly phenotypic correlation between traits were found to be highly significant (P<0.01 ).
