Snapdragon Flower Color Incomplete Dominance

Snapdragons homozygous for the allele for red flower color have the genotype frfr and have red flowers.

Snapdragon flower color incomplete dominance. This pattern of inheritance is described as incomplete dominance meaning that neither of the alleles is completely dominant over the other. Let s understand the incomplete dominance with the example of snapdragon flower antirrhinum sp. The gene for flower color in snapdragons displays incomplete dominance.

This is called as incomplete dominance. The heterozygous genotype is expressed as pink. What percentage of the offspring is expected.

Both alleles can be seen at the same time. There is blending of the two alleles. The results of a cross where the alleles are incompletely dominant can still be predicted just as with complete.

Generation will be pink in colour due to mixing of the alleles. The flowers in the f1. Monohybrid cross was done between the red and white coloured flowers of snapdragon plant.

Snapdragons homozygous for the allele for white flower color have the genotype fwfw and have white flowers. Heterozygous snapdragons with the genotype frfw have pink flowers. The two alleles are red r and white w.

The red flower is the dominant character and the white flower is recessive character. In snapdragons flower color is controlled by incomplete dominance. R red flower and r white flower if it is rr and had imcomplete dominance the flower will be pink because both traits will be shown.
