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.
