Example #2: In peas, purple flowers are dominant to white and tall are dominant to short. A white and short plant is crossed with a plant that is
heterozygous for both traits. Determine the phenotypic ratio.

Ras is a g-protein that is activated when a growth factor attaches to egfr. its activation results in the replacement of a gdp molecule with a gtp molecule, thus allowing a signal transduction pathway to be activated. considering the signal pathway illustrated on this page, what is one potential outcome of a mutation in the ras gene that leads to ras protein hyperactivity. be specific.
