Crossing over always occurs between the genes but never within them. Parts of gene cannot function. This study also describes the sequence variation between different Sr22 alleles, which may be due to intra-allelic recombination. The science of evolution The process of evolution Evolution as a genetic function The concept of natural selection. Human genetic variation is often biologically relevant, particularly when it influences (or is influenced by) health outcomes.
