GM 'surrogate hens' could lay eggs of rare chicken breeds, scientists say

Radical plan to maintain diversity of gene pool proposes use of genetically modified chickens as surrogate mothersTheRumpless Game is squawky and, as its name suggests, lacks a tail, while theBurmese Bantam, has fantastically flared leg feathers and a head like a feather duster. But the true value of rare chicken breeds, according to a team of scientists working to save them from obsolescence, is not their decorative crests and plumage, but the diversity they bring to the chicken gene pool.In a radical plan to preserverare varieties such as theNankin,Scots Dumpy andSicilian Buttercup, scientists at the the University of Edinburgh ’s Roslin Institute have bred genetically modified chickens designed to act as surrogates that would be capable of laying eggs from any rare breed.Continue reading...
