Genetic basis for remating in Drosophila melanogaster. V. Biometrical and planned comparisons analyses.
Drosophila melanogaster lines previously selected for fast and slow return of female receptivity were crossed to produce 16 lines (2 parental, 2 F1, 4 F2, and 8 backcross lines). Several genetic hypotheses could be tested both through particular planned comparisons among these 16 crosses and with a biometrical analysis. Both analyses identified the difference between the fast and the slow remating speed in these lines as having an autosomal basis. This is in agreement with observations from previous chromosome-substitution analyses. However, the planned comparisons yielded no significant deviations from expectations based on no dominance, no X-chromosomal factors, and no permanent cytoplasmic factors, whereas the biometrical analysis yields the best fit when some of these factors are included.
