Dear all, Please keep up the fascinating discussion of genetics/virus/asexual propagation. I am learning a lot. I wonder if both "clonal breakdown" and certain symptoms usually attributed to "virus" are not the result of an accumulation of transposons (and other nucleic hijinks) in the absence of sexual reproduction? Best, Max Withers PS: Although turkeys are not yet produced from tissue culture, the commercial breeds are incapable of sexual reproduction without human intervention.
