Show transcribed image text Passage lI Species A plants can have either white flowers or purple flowers. Gene W and Gene P are 2 of the genes that contribute to flower color in Species A plants. Gene W and Gene P each have a dominant allele, W and P. respectively that produces a functional enzyme. Gene W and Gene each have a recessive allele, w and p, respectively, that pro- duces a defective enzyme. Figure 1 shows the biochemical pathway that pro- duces the pigment in purple Species A flowers. Each rec- tangle represents a compound produced and/or converted in the pathway. Each oval represents an enzyme needed to catalyze the conversion of one compound into another. This enzyme is coded for by Gene P This This enzyme is coded for b Gene is coded for by Gene W purple Compound X (colorless) Compound Y (colorless) pigment (colorless) -→ (colorless)- →I Compound Figure 1 A student conducted the following crosses with Table 1 Species A plants to study the role of Gene W and Gene P in flower-color inheritance.
