Sex-linkage in the silver spangled Hamburg fowl
… of the Silver Spangled Hamburg is inherited as a sex-linked character belonging to the Abraxas type, although the inheritance may be modified by the presence of disturbing factors." -- Page 21.

Adaptive evolution, sex-linkage, and gene conversion in the voltage-gated sodium channels of toxic newts and their snake predators
… describe how genomic rearrangements have led to sex-linkage of four of the voltage-gated sodium channel genes in snakes and compare allele frequencies across populations and sexes to make inferences about how sex linkage has influenced the evolution of resistance in garter snakes. By measuring …

Genetic architecture of reproductive and growth traits in laboratory mice
… of additive, dominance, epistatic, maternal and sex-linkage effects for reproduction and growth traits in mice. Two selected lines of mice, extremes in phenotype for gain from 21 to 42 days of age, were used in a triple test cross design. The high line had completed 24 generations of selection …

Correlated response and sexual dimorphism in bidirectional selection experiments
… traits, and (2) the study of the inheritance of sexual dimorphism or body weight. The first experiment included data from four generations of double two-way selection for body weight and breast angle at eight weeks of age. Breast angle was considered a correlated trait in the weight subpopulation …

Evolutionary Genetics of Dictyostelids: Cryptic Species, Sociality and Sex
… project, I looked at whether D. discoideum has sex in natural populations. While sex has been observed in laboratory clones of D. discoideum , it is unclear whether sex occurs in natural populations, and sex can influence the evolution of traits. I used a dataset of microsatellites in 24 clones …

Genetic modification of the homomorphic sex chromosomes in the yellow fever mosquito Aedes aegypti provides novel insights and tools for biocontrol
… transmit pathogens, efficient and accurate sex separation of the non-biting males from the biting females is essential. Genetic sexing strains often rely on marker genes linked to the sex chromosomes. Sex linkage is more challenging in Ae. aegypti than many other species due to the …

Expanding Genetic and Genomic Resources for Sex Separation and Mosquito Control Strategies
… three innovative strategies for mosquito sex separation by exploiting several sex-linked marker lines. We show that by linking a transgenic marker to the male-determining locus (M locus), or by linking the male-determining Nix gene to a marker, males can be precisely separated from …
