Fig. i6.—Parents and Fj progeny of a cross between two races of the ladybird Epilachna chrysomclina showing polygenic segregation in respect of the black flecks and the dark colouring between them (after Bauer and Tiniofeeff-Ressovsky, 1943). frequency distribution of the Fg will cover a wider range, have a larger spread, than those of the individual parent lines and F^. In biometrical terms the F2 should have a larger variance than parents or Fj, because this variance will have a new, heritable component 69. Please note that these images are extracted fro
