Solution

The correct option is E $25$
A monohybrid cross is a cross between two individuals with different alleles at one genetic locus. If we cross two heterozygous individuals (Aa), then the percentage of offsprings with recessive phenotype will be:
Aa x Aa = AA Aa Aa aa, so recessive phenotypes would be 1/4 = 25%. Thus, the correct answer is option D.
