Reinforcement and sex linkage.
We present a general model for the effect of sex linkage on the evolution of reinforcement of mating preferences on an island. We find that the level of reinforcement can vary up to 80% depending on the mode of inheritance of the female preference and male trait. When reinforcement is driven mainly by selection in the male trait and intrinsic hybrid incompatibilities are weak, sex-linked prefer...
متن کاملSexual selection and sex linkage.
Some animal groups, such as birds, seem prone to extreme forms of sexual selection. One contributing factor may be sex linkage of genes affecting male displays and female preferences. Here we show that sex linkage can have substantial effects on the genetic correlation between these traits and consequently for Fisher's runaway and the good-genes mechanisms of sexual selection. Under some kinds ...
متن کاملLinkage mapping of sex-specific differences.
Most current linkage analyses assume identical fractions of meiotic recombination between homologous marker loci of the two sexes. This assumption is not realistic, because considerable sex-related differences have been observed in recombination fraction. In this paper, a general EM-based algorithm is presented to estimate sex-specific recombination fractions for a mixed set of molecular marker...
متن کاملRoot fusion in molars: incidence and sex linkage.
The study was done to determine the incidence and distribution of root fusion in 1340 maxillary and mandibular molars in 170 patients. A second objective was to determine whether root fusion of molars is sex-linked. A substantial percentage, 29% of all molars, had fused roots. Root fusion was found more frequently in maxillary than mandibular molars, 35% to 24%, and it occurred in many patients...
متن کاملConsensus and comprehensive linkage maps of the bovine sex chromosomes.
ory were 627, 2343, 972, 4577 and 1149, respectively. The number of marker loci submitted by each laboratory were 3, 5, 8, 23 and 10, respectively. A total of 9668 informative meioses from 30 microsatellite loci were represented in the combined data containing a total of 15 757 marker genotypes. Each data set was analysed independently using the TWOPOINT, FLIPS and CHROMPIC options. Genotypic d...
