Recessive gene and only double copies are barren maybe?The issue was exposed a hundred years ago but it’s never been tackled and so is a lingering problem, F&M drastically reduced the numbers and it would seem the incidence has increased. You would think a gene that caused females not to breed would naturally sort itself out but it would seem it’s a lot more complicated than that
