Question

You are exploring the jungle and find a new species of plant. Some of the flowers are red and some yellow. If the inheritance pattern is codominant what would you expect the heterozygous phenotype to be?

Answer 1

The expected e heterozygous phenotype would be orange.

Codominance is a type of non-Mendelian inheritance in which both alleles of one genotype are simultaneously expressed. So, in this example if allele A is responsible for red flower color and allele a for yellow flower color, Aa genotype (both alleles) will give both colors (red and yellow mixed together give orange).
