1)   What is the probability of GGRrTT in the progeny of a F1 cross?

2)   If you were to develop a Punnett square for the trihybrid cross GgRrTt x GgRrTt, how many times would you expect to see the genotype in question a) in the punnett square? c) If you were to calculate the odds of getting two homozygotes and one heterozygote would your answer be different and if different, what would be the value. What rule would you apply in a) and c)
