Unfortunately, the vast majority of research on parthenogenesis was conducted over 30 years ago by mostly a single scientist, M. W. Olsen, and almost entirely on a single noncommercial strain of turkey, the BSW turkey. More recently, a single study in 1998 found that 4% of the unfertilized eggs from modern commercial turkeys exhibited parthenogene-sis. A limited amount of very old parthenogenesis research with chickens does exist. About 15% of the freshly laid unfertilized eggs of Barred Plymouth Rock and White Leghorn hens exhibit embryonic development, but this development ceases when the eggs are incubated. Most infertile chicken eggs that develop embryos are from Dark Cornish, Silver Cor-nish, or Cornish crosses. Because of its breast con-formation, the Cornish chicken was used extensively to develop the modern day broiler breeder chicken. Therefore, it is very possible that the gene or genes controlling parthenogenesis in the Cornish chicken were passed on to the modern day broiler breeder.In fact, genetic selection drastically increases the inci-dence of parthenogenesis in turkeys. Parthenogene-sis in the BSW turkey was increased by genetic se-lection from 16.7 % in 1952 to 46 % in 1963. How-ever, research on genetic control of or genetic selec-tion for parthenogenesis in modern day poultry does not exist.

Аз какво казвах за "бъговете" - селекцията при партеногенезиса ги изхвърля, като при това се покачва процентът на излюпените неоплодени яйца.

Добре, че поне за влечугите признаваш партеногенезиса.

Не били ембриони хидатидите!
