Sexual selection drives faster evolution in males. The X chromosome is potentially an important target for sexual selection, because hemizygosity in males permits accumulation of alleles, causing tradeoffs in fitness between sexes. Hemizygosity of the X could cause fundamentally different modes of inheritance between the sexes, with more additive variation in males and more nonadditive variation in females. Indeed, we find that genetic variation for the transcriptome is primarily additive in males but nonadditive in females. As expected, these differences are more pronounced on the X chromosome than the autosomes, but autosomal loci are also affected, possibly because of X-linked …


A Simple And Improved Pcr-Based Technique For White-Tailed Deer (Odocoileus Virginianus) Sex Identification, Alec R. Lindsay Ph. D., Jerrold L. Belant May 2007

A Simple And Improved Pcr-Based Technique For White-Tailed Deer (Odocoileus Virginianus) Sex Identification, Alec R. Lindsay Ph. D., Jerrold L. Belant

Faculty Works

We describe a simple single-reaction technique for identifying the sex of white-tailed deer (Odocoileus virginianus) based on the PCR amplification of a zinc-finger intron using one pair of primers. Although Sry-coamplification confirmed sex identities, use of the Sry marker was unnecessary due to dimorphic alleles on the X and Y chromosomes at the zinc-finger locus. Insertions in intron 7 of the Y-linked allele (417 bp) make it nearly twice as long as the X-linked allele (236 bp) and thus the amplification products are easily discernable by simple agarose gel electrophoresis. The relatively short size of these products makes them useful …

Shark Bay Prawn And Scallop Fisheries. Draft Review Report, Department Of Fisheries Western Australia Apr 2007

Shark Bay Prawn And Scallop Fisheries. Draft Review Report, Department Of Fisheries Western Australia

Fisheries management papers

In recent times, the Department of Fisheries has received representations from both sectors about the ongoing interaction of the fisheries and their respective management settings. As a result, a decision was made to comprehensively review the fisheries, taking into account matters of fishery sustainability and gear interactions, together with industry economics and market considerations. The review has also addressed research requirements to ensure an appropriate scientific basis for decision-making into the future.


A Molecular Evaluation Of The North American “Grassland” Sparrow Clade, John Klicka, Garth M. Spellman Apr 2007

A Molecular Evaluation Of The North American “Grassland” Sparrow Clade, John Klicka, Garth M. Spellman

Ornithology Program (HRC)

Because they share several morphological and ecological characters, the North American sparrow (Emberizidae) genera Ammodramus, Passerculus, and Xenospiza have historically been considered members of a well-defined “grassland” sparrow assemblage. Relationships among the 11 members of this group have been the subject of much taxonomic debate, yet no comprehensive molecular assessment of relationships has been done. We investigated these relationships using mitochondrial DNA sequence data that included complete cytochrome-b and ND2 genes. Phylogenetic reconstructions derived via parsimony, likelihood, and Bayesian methods were congruent. The grassland sparrows, as presently configured, are polyphyletic. Pooecetes gramineus, Amphispiza belli (but not A. …
