A purple lily flower has no dots on its petals and attracts beetles as pollinato

Question

A purple lily flower has no dots on its petals and attracts beetles as pollinators. A white lily flower has dots on its petals and attracts bees as pollinators. Both are pure-bred and are crossed with each other. The F1 progeny makes pink flower with dots on petals and attract both beetles and bees. If purple vs white (PP vs pp), no dots vs dots (dd vs DD), beetles vs bees (BB vs bb) are three traits determined by three genetic loci, please use recessive, co-dominance, incomplete dominance, and dominance to explain the relationship with these three traits.

Explanation / Answer

1. Purple v/s White:- It is the case of incomplete dominance because neither of the parental colour is expressed in F1 generation rather the intermediate colour pink is obtained (characteristic of incomplete dominance).

2. Dots v/s No Dots:-- It is the case of Dominance as the Dominant gene (D) shows it's character , that is appearance of dots on the petals and recessive gene(d) does not show it's character.

3. Beetles v/s Bees:- It is the case of Co-Dominance as both the parental characteristic are shown in F1 progeny that is both the insects are attracted.(characteristic of Co-Dominance)
