 A plant of genotype GGHH is crossed with another plant of the genotype gghh. If the F1 is test crossed, what percentage (%) of the test cross progeny will have the genotype gghh when the two genes are - (P) unlinked, (Q) completely linked with no crossing over, (R) 10 m.u. (genetic map unit) apart, (S) 24 m.u. apart?

Two character X and Y, both follow law of dominance due to 3:1 F2 phenotypic ratio monohybrid cross separately. If carry out dihybrid selfing cross for heterozygous genotype for both character does not follow law of independence assortment in normal environmental condition due to  these two loci for character are linked at 20 map unit as cis configuration. Which of the following proportional genotype that homozygous for all loci in F2 generation?
