genetic basis for mendel experiments
the phenotype apparent in the F1 generation are dominant while the other phenotye which disappear ti the F1 generation but reappear in the F2 generation are recessive therefore the allele for round seeds and yellow cotyledons are dominant to those for wrinkled seed and green cotyledons respectively.
R represent the allele for round seed.
r represent the allele for wrinkled seed.
Y represent the allele for yellow cotyledon.
y represent the allele for green cotyledon.
