Cell specialization Chromosomes What is heredity and how do we acquire it? The team found eight separate cases in different species where these genes moved from sex chromosomes to autosomes. Members of the Sarcophagidae and Calliphoridae are the main invertebrate consumers of vertebrate carcasses Braack, C-banding revealed variably stained segments along the length of these chromosomes.

Speciation in ninespine stickleback: In such cases, we say that within this family the expressivity varies. Our findings indicate that porous species boundaries can trigger rapid sex chromosome evolution.
