Figure 1.

Sex phenotype distributions among Fragaria chiloensis offspring of HM1 × SAL3 cross. Male function is defined as the ability (male fertility, blue) or inability (male sterility, pink) to produce mature pollen and is a binary trait found in approximately half of the progeny. Female fertility is defined as the proportion of flowers producing fruit, and has a continuous, though bimodal, distribution, shown here partitioned into bins of 5%. Male and female function are highly negatively correlated, with nearly all male‐fertile offspring showing < 50% female fertility, and nearly all male‐sterile offspring showing > 50% female fertility.
