In boreal daisies, flower color is controlled by a gene at locus B. Daisies with at least one Ballele have blue petals, and daisies with the homozygous recessive bb genotype have yellow petals. A true-breeding daisy with blue flowers is crossed with a yellow daisy, and the F1 offspring are allowed to self-pollinate. The Punnett square below shows the predicted F2 offspring, where the numbers 1-4 represent the offspring corresponding to each box within the square. b. 4 Which of the offspring would have yellow flowers? O 1, 2, and 3 1 only 4 only 2 and 3 2. 1. 3.
