The degrees of freedom for the Ftest of "Marker Type" were 3 for the numerator and 37, and 33, for the denominator of swarm size and total couples, respectively (four swarms with size estimates had no complete measurement of total couples). ^{a}F denotes that the standard Ftest for fixed effects and Z denotes WaldZ tests for the covariance parameter estimates
