analysis is to look at three loci simultaneously so that we can determine their relative order on the chromosome. More important, we can also analyze the effects of multiple crossovers, which cannot be detected in a two-point cross, on map distances. Two crossovers between two loci can cause the chromosome to look as if no crossovers took place, causing us to underestimate map distances. Thus we need a third locus, between the rst two, to detect multiple crossover events.
Banded
Three-Point Cross
Analysis of three loci, each segregating two alleles, is referred to as a three-point cross. We will examine wing morphology, body color, and eye color in Drosophila. Black body (b), purple eyes (pr), and curved wings (c) are all recessive genes. Since the most ef cient way to study linkage is through the testcross of a multihybrid, we will study these three loci by means of the crosses shown in

gure 6.6. One point in this gure should be clari ed. Since the organisms are diploid, they have two alleles at each locus. Geneticists use various means to present this situation. For example, the recessive homozygote can be pictured as
1. bb prpr cc 2. b/b pr/pr c/c
or or
b pr c b pr c b pr c b pr c
3. b pr c/b pr c
A slash (also called a rule line) is used to separate alleles on homologous chromosomes. Thus (1) is used tentatively, when we do not know the linkage arrangement of the loci, (2) is used to indicate that the three loci are on different chromosomes, and (3) indicates that all three loci are on the same chromosome. In gure 6.6, the trihybrid organism is testcrossed. If independent assortment is at work, the eight types of resulting gametes should appear with equal frequencies, and thus the eight phenotypic classes would each make up one-eighth of the offspring. However, if there were complete linkage, so that the loci are so close together on the same chromosome that virtually no crossing over takes place, we would expect the trihybrid to produce only two gamete types in equal frequency and to yield two phenotypic classes identical to the original parents. This would occur because, under complete linkage, the trihybrid would produce only two chromosomal types in gametes: the b pr c type from one parent and the b pr c type from the other. Crossing over between linked loci would produce eight phenotypic classes in various proportions depending on the distances between loci. The actual data appear in table 6.1. The data in the table are arranged in reciprocal classes. Two classes are reciprocal if between them they contain each mutant phenotype just once. Wild-type and black, purple, curved classes are thus reciprocal, as are the purple, curved and the black classes. Reciprocal classes occur in roughly equal numbers: 5,701 and 5,617; 388 and 367; 1,412 and 1,383; and 60 and 72. As we shall see, a single meiotic recombinational event produces reciprocal classes. Wild-type and black, purple, curved are the two nonrecombinant classes.The purple, curved class of 388 is grouped with the black class of 367. These two would be the products of a crossover between the b and the pr loci if we assume that the three loci are linked and that the gene order is b pr c ( g. 6.7).The next two classes, of 1,412 and 1,383 ies, would result from a crossover between pr and c, and the last set, 60 and 72, would result from two crossovers, one between b and pr and the other between
