Legacy of a candidate gene and replication in genomics
During the 1990s and early 2000s, many human geneticists and other scientists (especially psychologists) tried to study the genetics of human traits by follo...

I always look through the table of contents of Nature Genetics, which I have delivered to my inbox. Over the last couple of years, the journal has included a...
The fundamental information about genetics for any individual is her genotype — the alleles that she has. But genes in populations can be considered in other...
Tall people tend to have tall parents. The height of the body, called stature, is one of the most obvious phenotypic traits in human populations. Anyone who ...
If everyone in a population lived a long life, mated, and reproduced absolutely equally (two offspring per person), then the population size would never chan...
The fundamental information about genetics for any individual is her genotype. The genotype for a single genetic locus is simply a list of two alleles, wheth...
Greg Mayer has a post on preformationism and epigenesis on the Why Evolution Is True blog:“Development is epigenetic”.
Gina Kolata writes an interesting story about the genetics of a pituitary giant (“New Story Writ by a Giant’s DNA”). The individual in question is a man know...

I pointed out the new treatment protocol for the sickle cell trait last week. In the interest of complete coverage of hemoglobinopathies, I’ll link to Scienc...
Many of us use sickle cell as an example in classes. I always do so while noting the progress that has been made in treating the condition in Westernized con...
