In four o'clock flowers incomplete dominance appears. cross two hybrid pinks. what will be the phenotypic ratio of the offspring?

Answer 1

1 red 2 pink 1 white

Answer 2

This all depends on what species you are referring to. With plants like in sweet peas, crossing a white flower with a red flower will give you a 100% phenoptyical chance of creating a pink flower. In animals where red is dominant and white is recessive, the phenotypical ratio of the offspring would be that 100% of the offspring are red.

However, if you are referring to animals that have incomplete dominance genes, like in Shorthorn cattle, breeding a red bull or cow with a white cow or bull will give you a roan calf where red and white hairs are expressed along with each other and not overpowering each other genetically. This will occur 100% of the time in each cross.

In the Charolais cattle breed, where the diluter gene is present (which is different from the better known Co-dominance or Incomplete Dominance gene), breeding a Charolais bull or cow with a red Shorthorn cow or bull will often result in a yellow or orange-coloured calf. Often even when a Charolais bull is crossed with a Hereford cow (or Hereford bull over a Charolais cow) will result in a buckskin or yellow coloured calf. The dilution gene in Charolais is different from the co-dominance or incomplete dominance gene, since this gene is responsible for creating offspring with colouration that is "diluted" from the colour of the parent that is lighter than the other parent. Incomplete dominance enables BOTH genes to be expressed at the same time, hence the roan colouration. Diluter gene is much less understood, and is supposedly expressed in a way that either colouration is mixed in some form or other.
