Question

1. The allele G for yellow stigma is completely dominant to green (g). Supposing
two strains of autotetraploid plants are available and their genotypes are as follows:
GGgg – in this plant the gene is close to the centromere
Gggg – in this plant the gene is far from the centromere

If these two plants are crossed:
a) provide the gametes that can be obtained from the two plants;
b) provide the genotypic and phenotypic ratios of the offspring. 

2. Consider the illustration below. Diagram the configuration you would observe at Anaphase I if crossing-over happens within the inversion. (IMAGE ATTACHED)
