Reinforcement of Gametic Isolation in Drosophila

Sperm retention in allopatric and sympatric females of D. yakuba.
A LMM was used to test for differences in sperm depletion/death over time between allopatric (A panels) and sympatric (S panels) lines of D. yakuba. The D. yakuba lines used in this experiment were SJ2 (brown), Cameroon 115 (blue), Anton 2 Principe (red), SA3 (light green), OBAT1200.15 (orange), and BAR1000.2 (dark green). I used six different D. santomea lines (tags highlighted in yellow) to make sure that the observed patterns were not line specific. Heterogeneity in slopes was detected between populations and was determined to be higher (i.e., faster sperm depletion/death) in sympatric than in allopatric lines.
