... Mendel only studied characteristics determined by single genes that had two alleles, one of which was dominant and the other recessive. Not all characteristics are determined by single genes which behave independently, as was the case in Mendel’s experiments. Sometimes, alleles express themselves eq ...

... If you were born in the UK, you have already been screened for a genetic disease. As in many other countries, a drop of blood is taken from the heel of every newborn baby, and sent off for lab tests.

Parblue? Turquoise? - Agapornis

... Lots of people have asked me to write an article about the ‘parblue’ mutation, and finally it’s here. The reason it took so long is because there is a lot of confusion over this mutation and to truly understand it, one must understand several other topics. There’s a lot to explain, and it will get s ...

Population genetics



Population genetics is the study of the distribution and change in frequency of alleles within populations, and as such it sits firmly within the field of evolutionary biology. The main processes of evolution (natural selection, genetic drift, gene flow, mutation, and genetic recombination) form an integral part of the theory that underpins population genetics. Studies in this branch of biology examine such phenomena as adaptation, speciation, population subdivision, and population structure.Population genetics was a vital ingredient in the emergence of the modern evolutionary synthesis. Its primary founders were Sewall Wright, J. B. S. Haldane and Ronald Fisher, who also laid the foundations for the related discipline of quantitative genetics.Traditionally a highly mathematical discipline, modern population genetics encompasses theoretical, lab and field work. Computational approaches, often utilising coalescent theory, have played a central role since the 1980s.
