... It is often convenient to store the flies you have collected and put 20 to 30 flies per vial. (Virgins should be used within 3 to 10 days). The best timing is to make crosses at Fri. The first progeny will emerge 10 days later, on Mon. During the storage period, it is also possible to ensure that yo ...

Brief Introduction of Single Nucleotide Polymorphism: Basic Concept

... One of the surprising findings of the Human Genome Project was that single nucleotide polymorphisms (SNPs), which, by definition, have a minor allele frequency greater than 1%, occur at higher rates than previously suspected. When occurring in the gene coding regions, SNPs can be synonymous (i.e., n ...

Molecular evolution

Molecular evolution is a change in the sequence composition of cellular molecules such as DNA, RNA, and proteins across generations. The field of molecular evolution uses principles of evolutionary biology and population genetics to explain patterns in these changes. Major topics in molecular evolution concern the rates and impacts of single nucleotide changes, neutral evolution vs. natural selection, origins of new genes, the genetic nature of complex traits, the genetic basis of speciation, evolution of development, and ways that evolutionary forces influence genomic and phenotypic changes.
