Unit 8 :
GENETICS
, a) Tallness (T) in snapdragons is dominant to dwarfness (t), while red (R) flower color
is dominant to white (r). The heterozygous condition results in pink (Rr) flower color.
If snapdragons are heterozygous for height as well as for flower color, a mating
between them will result in what ratio?
(1) 9:3:3:1 (2) 6:3:3:2:1:1.
(3) 1:2:1 (4) 27:9:9:9:3:3:3:1
