From: Two genomic regions together cause dark abdominal pigmentation in Drosophila tenebrosa
Abdominal pigmentation phenotypes in pure species mapping lines, hybrids and backcrossed individuals. (a) Parents and F1 offspring from reciprocal crosses. Flies from the pure species mapping stocks are denoted ‘P.’ For F1 hybrids, the female parent is listed first, where ST=D. suboccidentalis female × D. tenebrosa male, and TS=D. tenebrosa female × D. suboccidentalis male. (b) F2 offspring from backcross F1 hybrid female to D. suboccidentalis male and (c) F2 offspring from backcross of F1 hybrid female to D. tenebrosa male. See the text for details on the scoring of pigmentation.
