The green colour of leaves is dominant to yellow, and the segregation inF 2 takes place according to the 3:1 ratio.
The factor producing the “hukurin” is present in the parent with white flowers. This condition is dominant to full colour and inF 2 the segregation occurs according to the 3 : 1 ratio.
The results mentioned in 1 and 2 agree with those obtained by Takezaki.
If we denote the one parent by GGDD and the other by ggdd, there exists the interrelation between the factors G and D, inasmuch as in the presence of D the production of the dark-red flower-colour takes place when G is present in homozygous condition, and that of the red (magenta or scarlet) colour, when G is present in heterozygous condition or altogether absent. The hybridsF 1 (= GgDd) will thus bear always flowers of red (= magenta) colour.
