In Asia, dragon color shows incomplete dominance, where the dominant trait blends with the recessive trait.

If you cross two heterozygous green Asian dragons, what would be the genotype ratio of their offspring?

Question 1 options:

3 blue: 1 yellow


1 BB: 2 Bb: 1 bb


1 blue: 2 green: 1 yellow


1 Bb: 1 bb

B  BB  Bb
b  Bb  bb

BB = blue
Bb = green
bb = yellow

1 blue: 2 green: 1 yellow

Answer:

The correct answer would be 1 BB: 2 Bb: 1 bb

Let B and b be the alleles of the gene responsible for the color of the dragon.

The genotype of heterozygous dragon would be Bb.

So, the gametes produced by the parent would be B and b.

The cross is shown in the Punnett square.

It showed that the genotype ratio of the offspring came out to be 1BB : 2Bb : 1bb.
