Glycolysis is the series of reactions that produce ATP by converting glucose to pyruvate. The glycolysis pathway occurs in the cytoplasm of all cells, and it is the first steps in aerobic respiration. The reactions convert one six-carbon molecule of glucose to two three-carbon molecules of pyruvate. Each of the two pyruvate molecules that formed in glycolysis has two carbon–carbon bonds. The next two steps of aerobic respiration, acetyl-CoA formation and the citric acid cycle break both of these bonds. The energy released when the bond breaks is captured in electrons carried by NADH and in high-energy phosphate bonds of ATP. All the carbon atoms that were once part of glucose end up in CO 2 , which diffuses out of the cell.

Three of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results: Trait Number of individuals Wild type 169 Black 19 Black, hooked 301 Dumpy, hooked 21 Hooked, dumpy, black 172 Dumpy, black 6 Dumpy 305 Hooked 8 Determine the order of the genes and the mapping distance between genes. Determine the coefficient of confidence for the portion of the chromosome involved in the cross. How much interference takes place in the cross?

Genes at loci f, m, and w are linked, but their order is unknown. The F1 heterozygotes from a cross of FFMMWW x ffmmww are test crossed. The most frequent phenotypes in the test cross progeny will be FMW and fmw regardless of what the gene order turns out to be. What classes of testcross progeny (phenotypes) would be least frequent if locus m is in the middle? What classes would be least frequent if locus f is in the middle? What classes would be least frequent if locus w is in the middle?
