Frequencies of Ceruloplasmin Alleles in a Chinese Population
Human Heredity, 1985Plasma ceruloplasmin phenotypes were determined in a Chinese population. Among 1,042 unrelated persons examined, 3 appeared to be heterozygotes for an unidentified allele. Thus the frequency of the rare ceruloplasmin allele was estimated to be 0.0014.

Estimation of allele frequencies with data on sibships
Genetic Epidemiology, 2001AbstractAllele frequencies are generally estimated with data on a set of unrelated individuals. In genetic studies of late‐onset diseases, the founding individuals in pedigrees are often not available, and so one is confronted with the problem of estimating allele frequencies with data on related individuals.

Allele frequencies in a cat population in Budapest
Journal of Heredity, 1977Allelic frequencies were determined for the domestic cat population of Budapest, Hungary. Most of the frequencies are in the range of those of western European populations, but there are two unusual features. The first is the apparent absence of blotched tabby and a relatively high frequency of Abyssinian tabby.

Allele frequencies after a bottleneck
Theoretical Population Biology, 1984Abstract The effect that a recent change in population size (a “bottleneck”) has on the genetic composition of a random sample of genes is studied. The population is assumed to evolve as in the Wright-Fisher model with infinitely many neutral alleles.

The in vitro transmission frequency of the t6 allele
Nature, 1980The T region, located on chromosome 17 in the mouse, is a complex genetic locus which includes a series of recessive mutations, tn (refs 1, 2). These mutations include several alleles (also referred to as t-haplotypes2) which are embryonic lethals (tL). An additional phenotypic expression of the recessive lethal mutations is a distorted transmission of

Allele and Genotype Frequencies
2021Abstract An introduction to basic terminology in population genetics such as alleles, genotypes, and loci. This chapter introduces the basics of Hardy-Weinberg assumptions and predictions and explains how these assumptions can be used to provide insights and make basic inferences for real populations.

Pest Management Science, 2016
BACKGROUND The soybean looper (SBL), Chrysodeixis includens (Walker), is one of the most important soybean pests in Brazil. MON 87701 × MON 89788 soybean expressing Cry1Ac has been recently deployed in Brazil, providing high levels of control against the

Changes in allele and genotype frequency
2019Evolution is the change in heritable traits of populations over successive generations. At the molecular level this translates into changes in their genetic composition. A general theoretical investigation of how different demographic and evolutionary processes affect genetic variation within and between populations provides us with tools to ...

The allele frequency net database (AFND, http://www.allelefrequencies.net ) is an online web-based repository that contains information on the frequencies of immune-related genes and their corresponding alleles in worldwide human populations. At present, the website contains data from 1784 population samples in more than 14 million individuals from 129

HLA-G Polymorphisms and Allele Frequencies in Caucasians
Human Immunology, 1998HLA-G, a nonclassical class I MHC molecule, is uniquely expressed on extravillous cytotrophoblasts of the maternal-fetal interface and is suggested to be essential for establishment of maternal-fetal immune tolerance. Although the level of polymorphism in HLA-G has originally been considered low, number, nature and site of polymorphisms seem to vary ...
