Call for Mendel’s Garden #26 Submissions

The 26th edition of Mendel’s Garden will be hosted by A Free Man on December 7. If you have written a blog post about any topics in Genetics in the past month or so, send a link to Chris (chris[at]afreeman[dot]org) to be included in the carnival. We’re also looking for hosts for upcoming editions. If…

Genome Sequenced, Published via Press Release

Back in the day, you could sequence a genome and get a Nature paper out of it. Pretty soon, the sexiness of genome sequencing wore off, and it took a bit more to get into a vanity journal. You had to sequence something cute and cuddly, something extinct, or a lot of genomes at once.…

Is Nested Clade Analysis Worthwhile?

Population biologists often want to infer the demographic history of the species they study. This includes identifying population subdivision, expansion, and bottlenecks. Genetic data sampled from multiple individuals can often be applied to study population structure. When phylogenetic methods are used to link evolutionary relationships to geography, the approaches fall under the guise of phylogeography.…

Genes in the Post-Genomic Era

You would think that geneticists would have a good definition of “gene”. After all, genes are what we study. In introductory biology courses, you may have been introduced to the concept of the gene as the unit of heredity. That’s all well and good, but when you begin to study genes at a molecular level…

I Voted . . . Blindly

If you hold on until the end of the post, you’ll see that it’s got science content. But you’ll have to wait until the end. First, here’s how it starts. I had an optometrist appointment at 8am this morning. I could have voted prior to the appointment, but the polling place is in between the…

Mendel’s Garden #25

After a few months off, here’s the return of Mendel’s Garden. Blast from the past: rENNISance woman gives us a post on viral genetics. Figuring out DNA looping with unbelievably advanced technology: Greg Laden reviews a paper on the structure of nucleic acids. In the fly, delayed reproduction also delays aging: Ouroboros describes research on…
