Explanation:

Step 1: Solve Question 1 (Genotype Classification)

• Homozygous (Ho): Genotype with identical alleles (e.g., AA, BB, aa).
• Heterozygous (He): Genotype with different alleles (e.g., Aa, Bb, Cc).

• AA: Ho (identical alleles)
• Ee: He (different alleles)
• Ii: He (different alleles)
• Mm: He (different alleles)
• Bb: He (different alleles)
• k: (Assume "k" is "kk" or "Kk"? If "k" is a typo, but likely homozygous (Ho) if single allele, but standard is two alleles. Maybe "kk" intended? For clarity, if "k" is "kk", Ho; if "Kk", He. But given context, likely Ho.
• Jj: He (different alleles)
• nn: Ho (identical alleles)
• Cc: He (different alleles)
• Gg: He (different alleles)
• kk: Ho (identical alleles)
• oo: Ho (identical alleles)
• DD: Ho (identical alleles)
• HH: Ho (identical alleles)
• LL: Ho (identical alleles)
• pp: Ho (identical alleles)

Step 2: Solve Question 2 (Phenotype Determination)

Flower Color (Purple dominant to White)

• PP: Dominant allele present → Purple flowers
• Pp: Dominant allele present → Purple flowers
• pp: Recessive alleles only → White flowers

Eye Color (Brown dominant to Blue)

• BB: Dominant allele present → Brown eyes
• Bb: Dominant allele present → Brown eyes
• bb: Recessive alleles only → Blue eyes

Seed Shape (Round dominant to Wrinkled)

• RR: Dominant allele present → Round seeds
• Rr: Dominant allele present → Round seeds
• rr: Recessive alleles only → Wrinkled seeds
