Quantitative genetic analysis of salivary gland infection barrier in Aedes aegypti. Each analysis corresponds to one of the seven virus strains tested for log₁₀(PFU)/salivary gland. 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.

σ²s = average variance among offspring of a single sire; h² = narrow-sense heritability (h² = Va/Vp). * p = 0.03–0.05, ** p = 0.001, *** p < 0.00001.
