Question

A certain species of lizard can have orange stripes, green stripes, or orange and green stripes. An GG lizard has orange stripes, a gg lizard has green stripes, and a Gg lizard has orange and green stripes. This is an example of which type of inheritance?

Answer 1

Codominance

Step-by-step explanation:

In some examples, one allele is dominant to another one. This means that it will be expressed over its recessive counterpart. So if an individual carries a dominant and a recessive allele, they will show the dominant phenotype. To display the recessive phenotype, the genotype must not have the dominant allele, and have 2 copies of the recessive gene instead.

In this case, heterozygotes express both alleles. This is an example of codominance. In codominance, neither allele is dominant/recessive, and the phenotypes of both alleles are expressed in heterozygotes
