Quantitative genetic analysis of SGEB in Aedes aegypti. Each analysis corresponds to one of the seven virus strains tested for log10(PFU)/saliva. We used PROC MIXED in SAS to obtain restricted maximum likelihood (REML) to estimate quantitative genetic parameters. The greater the variance in sire means, the larger the heritability.
