Question

In dragons, green scales are dominant to brown scales. A mating between a dragon with green scales and a dragon with brown scales produces offspring with a speckled pattern of green and brown scales. What are the genotypes of the two parents and the offspring?

Answer 1

Answer:

The correct answer would be -

parent 1: GG

parent 2: gg

offspring: Gg

Explanation:

Let assume the dominant allele of the dragon scale is represent by G and the recessive allele that expressed in brown is represented by g. As it is given that offspring by mating is expressing this trait as a speckled pattern of both alleles brown and green which means it shows codominance where both alleles expressed together in offspring if present in heterozygous condition.

So, the cross between GG and gg will result in a heterozygous combination to produce offspring with a speckled pattern of brown and green scales.

The correct answer would be -

parent 1: GG

parent 2: gg

offspring: Gg
