In a certain breed of plants, dark green is determined by the dominant gene 'G' and light green is determined by the recessive gene 'g'. The heterozygotes show 75% penetrance. If the parental cross GG x gg was made, how many of each of the expected phenotypes will be observed in a population of 400 F2 plants? How many dark green and light green plants are there?
