Detailed explanation-1: -Of these three genotypes, only bb, the homozygous recessive genotype, will produce a phenotype of blue eyes.
Detailed explanation-2: -Offspring whose genotype is either AA or Aa will have the dominant trait expressed phenotypically, while aa individuals express the recessive trait.
Detailed explanation-3: -One gene is for ear size (AA or Aa being big ears whereas aa is for small ears) and the other gene is for buggy eyes (BB and Bb for buggy eyes whereas bb represents normal eyes).
Detailed explanation-4: -If the pairs are heterozygous, one will always dominate the other. Law of dominance explains that in a monohybrid cross between a pair of contrasting traits, only one parental character will be expressed in the F1 generation and both parental characters will be expressed in the F2 generation in the ratio 3:1.
