The Punnett square below shows a cross, indicating genotypes of the male and female parents and those of embryos born from this cross. The germ-cell-less gene encodes a component of the pole plasm in Drosophila. Which of the following statements is correct about the phenotypes of the embryos? father G g G G/G G/g 9 G/g g/g Alleles: G = wild type allele of germ-cell-less g = mutant allele of germ-cell-less G/G and G/g embryos will be normal, g/g embryos will have PGCs at the posterior and anterior poles G/G, G/g and g/g embryos will have PGCs at the anterior pole G/G, G/g, and g/g embryos will be normal G/G, G/g and g/g embryos will not have PGCs at the posterior pole G/G and G/g embryos will be normal, g/g embryos will have no PGCS mother
