What is the expected genotypic ration resulting from a zygous dominant x heterozygous monohybrid cross?

When you cross AA and Aa the possible genotypes are AA, Aa, AA, and Aa, making for a 2:2 ratio which reduces to 1:1 making the FINAL ANSWER B. Remember genotype is the AA, Aa, etc. and phenotype is green, tall, large, etc.
