In bone marrow, stem cells are committed to different lineages. Factors that stimulate colonies of these different lineages are interleukin-3 (multi-CSF), IL-7,  granulocyte- macrophage colony stimulating factor (GM-CSF) and granulocyte or macrophage colony- stimulating factor (G-CSF or M-CSF). In a mouse deficient in IL-7 the number of which cells will not be altered

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?
