ChickensGenomic structureSelectionHere, we have evaluated the general genomic structure and diversity, and studied the divergence resulting from selection and historical admixture events for a collection of world﹚ide chicken breeds. In total 636 genomes (43 populations) were sequenced from chickens of ...
alleles.The genetic variation in general had been reduced significantly within families.However,the change of mating scheme from within families to between families since the F15 generation could have converted the positive inbreeding FIS values to negative out-breeding FIS estimates in most families(7...
Greater prairie-chickens (Tympanuchus cupido pinnatus) were once found throughout the tallgrass prairie of midwestern North America but over the last century these prairies have been lost or fragmented by human land use. As a consequence, many current populations of prairie-chickens have become iso...

Chickens were bred to eat less, grow to maturity in a shorter time, and produce more eggs. As a result of such scientific advances, our twelve Midwestern states alone now feed one-fourth of the world’’s people. Crop disasters in 1972 brought an apparent end to the growth in production...
