11. Cross Aa × Aa. A is completely dominant over a; assume equal gamete probabilities and random fertilisation. What percentage of offspring is expected to show the recessive phenotype? (2 marks)
25%
Four equally likely allele pairings: AA, Aa, Aa, aa. Only aa shows the recessive phenotype: 1/4 × 100 = 25%. This is a probability, not a guaranteed count.
12. Cross Aa × AA. A is completely dominant over a; assume equal gamete probabilities and random fertilisation. What percentage of offspring is expected to show the recessive phenotype? (2 marks)
0%
Four equally likely allele pairings: AA, AA, Aa, Aa. Only aa shows the recessive phenotype: 0/4 × 100 = 0%. This is a probability, not a guaranteed count.
