In africa, dragon color is co-dominant. the colors blue and yellow are co-dominant. if you cross a yellow dragon with a blue/yellow dragon. what would be the phenotype ratio of their offspring ? i don't understand the co-dominant punnet squares, so explain it so that i can do them on my own in the future : ) you! a- 1 blue and yellow: 1 yellow b- 1 green: 1 yellow c- 1 blue: 2 blue and yellow: 1 yellow d- 3 blue: 1 yellow

The answer is; A

Let us assign the allele for Blue dragon color as B and that of Yellow dragon color as Y and create the punnet square below;

The phenotypic ratio will, therefore, be;

1 Yellow/Blue : 1 Yellow

Option A

Explanation:

In co-dominance,  two different traits associate with each other to produce an intermediate trait combining the characteristic of the two individual traits.

For example -

If red color flower is crossed with white color flower, then its co-dominated offspring would be oink in color.

Here -

Genotype of  yellow dragon is YY

Genoype of yellow/Blue dragon is YB

YY * YB

YY, YB, YY, YB

Out of four off spring 2 are yellow and 2 are yellow/blue

So the ration of yellow and yellow/blue offspring are

2: 2

1: 1

Hence, option A is correct
