haploidy, diploidy, polyploidy … not a problem

Investigating pairwise relatedness is fundamental to the characterization of the mating system and inferring genetic structure. If no pedigree exists, then relatedness is estimated from genetic markers (e.g., microsatellite loci) using method-of-moment or maximum-likelihood methods. However, not all individuals in … Continue reading

Sweeping for Sweeps

Reduction in genomic diversity around a site has been attributed to one of two mechanisms – (1) sites linked to positively selected mutant alleles are often `swept’ to fixation, in a process often called genetic hitchhiking, and/or (2) background selection … Continue reading

A molecular how-to for hibernating this winter

As the academic semester ends, I see the tell-tale signs of the upcoming holiday hibernation. The weary eyes of teaching assistants peeking over piles of final exams. Students who may have mentally been on break before finals even started. A little … Continue reading

Totally RAD

Puritz et al. (2014) weigh the pros and cons of, the aptly titled, “RAD fad” in a comment recently published online in Molecular Ecology. They challenge: (1) the assertion that the original RAD protocol minimizes the impact of PCR artifacts … Continue reading

Identifying and correcting errors in draft genomes

Over the past decade we have seen an exponential increase in the number of sequenced, assembled, and annotated genomes. These these genomes are essential for pretty much any genomics research. If you want to sequence the genome, transcriptome, epigenome, or … Continue reading

Exotic gene flow surveillance

Exotic forest plantations often cover large areas and, as such, may contribute female gametes, male gametes and/or zygotes to native stands. In seed plants, these three components of exotic gene flow have not been distinguished, though they will have different … Continue reading

How prevalent are non-overlapping generations?

Recently, the question of how prevalent in nature are truly non-overlapping generations has piqued my interest. There are many methodologies which make the assumption that generations are non-overlapping. Or in other cases, it is a simplification we may make to … Continue reading
