Population Genetics Undergrad Class

We’re teaching Population and Quantitative Genetics (undergrad EVE102) this quarter. We’re posting our materials here, in case they are of interest.

A pdf of the popgen notes is here

The slide pdfs are linked to below

Lecture One [Introduction and HWE]. Reading  notes up to end of Section 1.2.

A Genealogical Look at Shared Ancestry on the X Chromosome

Congratulations to Vince on the publication of his paper “A Genealogical Look at Shared Ancestry on the X Chromosome”, which has been published in Genetics . In this paper, in collaboration with Steve Mount and myself, he explores how the transmission properties of the X chromosome make it useful for learning about relationships between close relatives. It is available on the bioRxiv. You can read Vince’s  blog post on this here, and watch his talk at Evolution on this topic.

A: Simulated X genealogy of a present-day female, back nine generations. Each arc is an ancestor, with female ancestors colored red, and male ancestors colored blue. The transparency of each arc reflects the genetic contribution of this ancestor to the present-day female. White arcs correspond to an X genealogical ancestor that shares no genetic material with the present-day female, and gray arcs are genealogical ancestors that are not X ancestors.

Nancy’s biology of genomes talk

Nancy presented her work on the genomics of short-term selection in the Florida Scrub Jays  at the CSHL Biology of genomes meeting. You can read a writeup of the work here.

Nancy’s talk was wonderfully illustrated by Alex Cagan:
