True/False
Indicate whether the statement is true or false.
 

 1. 
Structure Your Knowledge #3     Does the following statement answer the question?
Always look at the F1 heterozygote resulting from a cross of true-breeding parents. If alleles show complete dominance / recessiveness, then the heterozygote will have a phenotype identical to one parent. In incomplete dominance, the F1 phenotype will be intermediate between that of the parents. If codominant, the phenotype of both allleles will be exhibited in the heterozygote.
 

Multiple Choice
Identify the choice that best completes the statement or answers the question.
