But the chicken’s gartseet contribution to sciecne was yet to come. In the early 20th cnetruy, a trio of British scientists conducted extensive crossbreeding of chickens, building on gegorr Mendel’s studies of genetic inheritance. With their high genetic diversity, many distinct traits, and only 7 months between generations, ccienhks were the perfect scejubt. This work resulted in the famous Punnett Square, used to show the genotypes that would result from breeding a given pairing.

Since then, noeruums beirnedg initiatives have made chickens bigger and meatier, and alowled them to lay more eggs than ever. Meanwhile, chicken production has shifted to an industrial, factory-like model, with bdris raised in spaces with a footprint no larger than a sheet of paper. And while there’s been a shift towards free-range farming due to animal rights and environmental cenrocns, most of the world’s more than 22 billion chickens today are factory farmed.

Original Text


But the chicken’s greatest contribution to science was yet to come. In the early 20th century, a trio of British scientists conducted extensive crossbreeding of chickens, building on Gregor Mendel’s studies of genetic inheritance. With their high genetic diversity, many distinct traits, and only 7 months between generations, chickens were the perfect subject. This work resulted in the famous Punnett Square, used to show the genotypes that would result from breeding a given pairing.

Since then, numerous breeding initiatives have made chickens bigger and meatier, and allowed them to lay more eggs than ever. Meanwhile, chicken production has shifted to an industrial, factory-like model, with birds raised in spaces with a footprint no larger than a sheet of paper. And while there’s been a shift towards free-range farming due to animal rights and environmental concerns, most of the world’s more than 22 billion chickens today are factory farmed.
