Snapdragon Flower Color Inheritance Pattern. As a result of codominance, roan cattle show both red and white hair on their skin. When the f1 offspring are crossed, you get the following numbers of f2 offspring:
In snapdragon a cross between true breeding red flowered plant (rr) and true breeding white flowered plant (rr) will result in the progeny being heterozygous (rr) and having pink flowers. Thomas hunt morgan mapped this trait to the x chromosome in 1910. Different flower colors in snapdragons arise by the incomplete dominance.
(ii) inheritance pattern of flower colour in snapdragon is given below:
In spain, where snapdragons grow wild, these flower colors show a remarkable pattern: Like humans, drosophila males have an xy chromosome pair, and females are xx. Looking at snapdragon flower color, if both parents had a pink flower, we would expect 50% of their offspring to have the pink color flower (heterozygous pink),. The two alleles are red (r) and white (r).
