There are a number of C. trachomatis gene products that exhibit variability and may modulate disease severity (Figure 3). The major categories of variable chlamydial gene products and their roles in ...

Rare genetic traits are features that are uncommon within the general population. They can lead to different observable features or to rare physical abilities. Rare genetic traits are typically ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...
