  • a Selection coefficients (s) of the mys genetic markers and effective population sizes (Ne) were estimated with model M1 and M5 from the relative frequency variations of marked N and S segments after a transmission episode with 1 or 10 aphids (CI, 95% credibility intervals). Selection coefficients show the relative fitness of the mys2 over mys7 markers for the N segment and of the mys8 over mys1 markers for the S segment. The values reported for Ne correspond to the mean of the zero-truncated Poisson distribution (using the λ parameter of the ZTP yields very close results).
