If two alleles influencing the expressed phenotype for a trait are equally expressed, this is an example of: a. polymorphism.b. codominance.c.Mendelian inheritance.d. pleiotropy.
Explanation:codominance inheritance is when both alleles of a heterozygous gene pair have full phenotypic expression. A good example is the human blood group; people with ABO blood group type AB blood have one allele for A and one for B both expressed.
