Sex-linked genes in age-structured populations 来自 Semantic Scholar 喜欢 0 阅读量: 29 作者:Cornette,L James 摘要: An official journal of the Genetics Society, Heredity publishes high-quality articles describing original research and theoretical insights in all areas of genetics. Research papers are...
Here, we use data on an array of different traits measured on over 10,000 individuals from two pedigreed populations of birds (collared flycatcher and zebra finch) to estimate the amount of sex-linked genetic variance (h2z). Of 17 traits examined, eight showed a nonzero h2Z estimate but ...
Both color patterns show single gene inheritance, and are dominantly expressed in both sexes, sex-linked and determined by different loci on the X- and Y-chromosomes. Alleles for the black caudal-peduncle (Bcp) and red tail (Rdt) loci, are dominant over that of the wild-type, Bcp^+ and...
A sex-linked gene, P, controls the onset of sexual maturity in the platyfish, Xiphophorus maculatus. The activity of this gene is correlated with the age and size at which the gonadotropic zone of the adenohypophysis differentiates and becomes physiologically active. Immature fish of all genotypes...
X-linked determinants of this pattern—recognized by variegation in females but not in males—have been described in the domestic cat as Orange, and in the Syrian hamster as Sex-linked yellow (Sly), but are curiously absent from other vertebrate species. Using a comparative genomic approach, ...
Although sex-specific selection is often hypothesized to shape the evolution of sex-linked and autosomal gene content, population genetics theory has yet to account for many of the gene-and lineage-specific idiosyncrasies emerging from the empirical literature. With the goal of improving the ...

The Genetics of the Fowl An investigation has been conducted to determine the mode of inheritance of frizzling in the domestic fowl and to substantiate or disprove the current theory that homozygosity for frizzling is lethal. Two types of frizzling, ordinary ... FB Hutt - 《Journal of Genetic...
I investigated the genetic background of intraspecific variation in oviposition specificity in the generalist butterfly Polygonia c–album. Using reciprocal crosses between two populations that differ in their degree of specialization, I show that specificity is strongly sex–linked. This indicates that ...
Through a progeny test of sex-reversed fish and a linkage analysis of isolated sex-linked DNA markers, we show that O. hubbsi, which is one of the most closely related species to O. dancena, has a ZZ/ZW system. In addition, genetic and fluorescence in situ hybridization mapping of the...
