Gene frequencies in Icelandic cats [PDF]

open access: yesHeredity, 1975
A survey of genetically determined coat polymorphisms of Icelandic cats, in Reykjavik and adjacent rural areas, has shown that these animals are quite distinct from cats previously studied in north-west Europe. The differences are interpreted to indicate that Icelandic cats represent a relict population reflecting the condition of north-west European ...

Analysis of Egg White Lysozyme Polymorphisms among Japanese Quail Populations in Japan and France

open access: yesThe Journal of Poultry Science, 2012
Japanese quail egg white lysozyme possesses two alleles (S and F). In our previous study, the F phenotype was more effective against bacteria than the S phenotype, whereas the female-derived S phenotype led to improved hatchability.

ANALYSES OF GENE FREQUENCIES [PDF]

open access: yesGenetics, 1973
ABSTRACT Models of variance components and their intraclass correlational equivalences are developed for genes falling into various categories of subdivisions within a population. Estimable functions are elaborated demonstrating that intraclass correlations can be estimated only relative to that for the least related genes in the ...

Variance of Gene Frequencies [PDF]

open access: yesEvolution, 1969
Inbreeding, gene frequency variance, and their corresponding effective population numbers are now commonplace terms in population genetics. The concepts and much of the theory are classical (Wright, 1921, 1931; Fisher, 1930). More recent refinements and extensions of the theory by Crow and associates (Crow, 1954; Crow and Morton, 1955; Kimura and Crow,

Prevalências das mutações 35delG/GJB2 e del (GJB6-D13S1830) em portadores de surdez não-sindrômica na população do Espírito Santo - Brasil Prevalence of 35delG/GJB2 and del (GJB6-D13S1830) mutations in patients with non-syndromic deafness from a population of Espírito Santo - Brazil

open access: yesBrazilian Journal of Otorhinolaryngology, 2010
Mutações no gene GJB2 constituem a principal causa de surdez genética de herança autossômica recessiva, sendo a mutação 35delG a mais comum em muitos grupos étnicos.

ANALYSES OF GENE FREQUENCIES OF MATES [PDF]

open access: yesGenetics, 1973
ABSTRACT A genic analysis of variance of data on mate pairs for a codominant gene is developed. This analysis provides estimators of the correlation, F, of genes within individuals, of the correlation, Θ, of genes between mates, and of various variances-all relative to the correlation or variation among genes of nonmates.

Construction of a droplet digital PCR detection system for platelet HPA-3 and HPA-15 genotyping

open access: yesZhongguo shuxue zazhi
Objective To establish a highly sensitive detection method of platelet HPA-3 and HPA-15 genotyping by droplet digital PCR (ddPCR), and to explore the feasibility of applying it to the detection of human platelet antigen (HPA) compatibility in maternal ...
