If 'A' represents the dominant allele and 'a' represents its recessive allele, which of the following would be the most likely result in the first generation offspring when Aa is crossed with aa?
All will exhibit dominant phenotype
All will be of recessive type
Dominant and recessive phenotype will be 50%
Dominant phenotypes will be 75%
The most likely result of such a cross will be 50% Aa offspring and 50% aa offspring.
