Answer

Explanation:

Step1: Analyze allele - combination rules

In a di - hybrid cross, we combine the alleles from the male and female gametes.

Step2: Determine genotype for 1

The column has 'eA' and the row has 'EA'. Combining them gives EeAA.

Step3: Determine genotype for 2

The column has 'EA' and the row has 'Ea'. Combining them gives EEAa.

Step4: Determine genotype for 3

The column has 'Ea' and the row has 'Ea'. Combining them gives EEaa.

Step5: Determine genotype for 4

The column has 'eA' and the row has 'eA'. Combining them gives eeAA.

Step6: Determine genotype for 5

The column has 'ea' and the row has 'ea'. Combining them gives eea.

Answer:

  1. EeAA
  2. EEAa
  3. EEaa
  4. eeAA
  5. eea
