Reciprocal crosses between males and females of the two selected GTLE and TLRE.

1leftover espression detected by in situ hybridization.The table shows the results from mating different GTLE females with different TLRE and wt males, and TLRE females with different GTLE and wt males. Only TLRE females could generate a higher frequency of larvae with reversed parapineal organ, independently from the male. n = number of embryos per each cross; left lov = number of embryos with stronger expression of leftover in the left habenula; right lov = number of embryos with stronger expression of leftover in the right habenula.
