Segregation and Replication of Chromosomes in Turkey Parthenogenesis

A STRAIN of Beltsville small white (BSW) turkeys developed at this station regularly produce eggs with a marked predisposition to develop parthenogenetically. More than 40 per cent of incubated unfertilized eggs laid by birds of this strain can reasonably be expected to undergo development at least to the degree where sheets of unorganized cells can be detected macroscopically when the eggs are broken^1,2.
