ln a population of turtles, there are yellow-green shells and green shells.  The yellow shells are caused by a homozygous recessive gene and the green shells are caused by the dominant gene.  Given the following data: AA = 340 Aa = 270 aa = 120                                           a)  Calculate p and q. b)  Use a chi square test to determine if these alleles are in Hardy-Weinberg equilibrium
