the chromosomes replicate, but the cell does not divide. In the salivary gland of the fruit y, homologous chromosomes synapse and then replicate to make about one thousand copies, forming very thick structures with a distinctive pattern of bands called chromomeres ( g. 6.12). Using methods chapter 8 will discuss, scientists have mapped many loci to particular bands. Part of the Drosophila chromosomal map is presented in gure 6.13 (see also box 6.2). Locate the loci we have mapped so far to verify the map distances. In summary, we know that two or more loci are linked if offspring do not fall into simple Mendelian ratios. Map distances are the percentage of recombinant offspring in a testcross. With three loci, determine the parental (nonrecombinant) and double recombinant groups rst. Then establish the locus in the middle, and recast the data in the correct gene order. The most accurate map distances are those obtained by summing shorter distances. Determine a coef cient of coincidence by comparing observed number of double recombinants to expected number.

event should entail the exchange of physical parts of homologous chromosomes. This can be demonstrated if we can distinguish between two homologous chromosomes, a technique Creighton and McClintock rst used in maize (corn) and Stern rst applied to Drosophila, both in 1931. We will look at Creighton and McClintock s experiment. Harriet Creighton and Barbara McClintock worked with chromosome 9 in maize (n 10). In one strain, they found a chromosome with abnormal ends. One end had a knob, and the other had an added piece of chromatin from another chromosome (fig. 6.14). This knobbed chromosome was thus clearly different from its normal homologue. It also carried the dominant colored (C) allele and the recessive waxy texture (wx) allele. After mapping studies showed that C was very close to the knob and wx was close to the added piece of chromatin, Creighton and McClintock made the cross shown in gure 6.14. The dihybrid plant with heteromorphic chromosomes was crossed with the normal homomorphic plant (only normal chromosomes) that had the genotype of c Wx/c wx (colorless and nonwaxy phenotype). If a crossover occurred during meiosis in the dihybrid in the region between C and wx, a physical crossover, visible cytologically (under the microscope), should also occur, causing the knob to become associated with an otherwise normal chromosome and the extra piece of chromosome 9 to be associated with a knobless chromosome. Four types of gametes would result ( g. 6.14).

Cytological Demonstration of Crossing Over
If we are correct that a chiasma during meiosis is the visible result of a physical crossover, then we should be able to demonstrate that genetic crossing over is accompanied by cytological crossing over. That is, the recombination

he rst chromosomal map ever published included just ve loci on the X chromosome of Drosophila melanogaster ( g. 1). It was published in 1913 by Alfred H. Sturtevant, who began working in Thomas Hunt Morgan s y lab while an undergraduate student at Columbia University. The y lab included H. J. Muller, later to win a Nobel Prize, and Calvin B. Bridges, whose work on sex determination in Drosophila we discussed in the last chapter. Sturtevant worked with six mutants: yellow body ( y); white (w), eosin (we ), and vermilion eyes (v); and miniature (m) and rudimentary wings (r). (White and eosin are actually allelic; Sturtevant found no crossing over between the two loci. ) Using crosses similar to the ones we outline in this chapter, he constructed the map shown in gure 1. The map distances we accept today are very similar to the ones he obtained. Sturtevant s work was especially important at this point because his data supported several basic concepts, including the linear arrangement of genes, which argued for the
