If two alleles of a gene are codominant, and an individual that is homozygous for one allele is crossed with an individual that is homozygous for the other: Group of answer choices epistasis is occurring. the two cancel each other out, and there is no phenotype in the offspring. offspring should only show phenotypes associated with the allele from the female parent. offspring should show phenotypes with full expression of both alleles.
