Two pure-breeding (homozygous) lines of shrubs were crossed as follows: P1 phenotype red leaves green leaves P1 genotype AA BB Fl phenotype 100% green leaves with white flecks F1 genotype _AB Crossing the F1s produced: F2 phenotypes F2 genotypes 123 green leaves w/white flecks 44 green leaves AB 63 red leaves BB
1. Get the total of the F2 generation
2. Divide the number of each phenotype with the total then multiply by 16 DO NOT round off the answer. Always write the phenotype beside the answer.
Determine the closest ratio according to type of gene interaction and Determine the type of gene interaction
