Figure 2. Branch diagram outlining the progeny expected from a cross between F1 males selected for Plum eyes and Stubble bristles (as shown in Figure 1), which also had a bushy phenotype, and pure-breeding females expressing all four unmapped recessive mutant traits. Curly (Cy), Plum (Pm), Dichaete (Di), and Stubble (Sb) are lethal markers with a dominant effect on phenotype that act as recessive lethals. The pure-breeding mutant females are homozygous wild-type for the lethal markers (cx+cX+ pm+pm+ di+di+ sb+sb+) and for all mutant traits. The Hh gene controls aggressiveness; while H-individuals are friendly, hh flies are mean. The speed at which flies move is controlled by the Ff gene; individuals with the F-genotype walk at normal speed, but ff flies move much faster. Flies with an A-genotype prefer fruit, but aa individuals select alcohol instead. Extra bristles make bb flies appear bushy, while B- individuals have a normal bristle number. NOTE: Draw all chromosomes for all possibilities. Include ratios for each branch. Male and female flies should be grouped. Use this diagram to complete Table 1.
