Answer»

Right option is (d) 10

For EXPLANATION: ACCORDING to normal dominant/ recessive relation the ratio between red and white flowers should be 3:1, but in the case of snapdragon where the heterozygous has a different phenotype pink the ratio changes to 1:2:1 for red: pink: white. Thus the EXPECTED NUMBER of red is 10.
