the two genes under consideration are on the same chromosome as shown below in the diagram and the parental combinations of alleles remain together unless separated by a recombination event The closer together two genes are the more likely they are to be inherited in the parental combination We can quantify this statement We define the Recombination Fraction theta
by TB 10 19 A four point testcross which localizes this gene between R and sr2 is presented in Table 1 using the modified testcross system of D S Robertson 1955 Genetics 40 746 760 Table 1 These data place the gene at 87 on the chromosome 10 linkage map Figure 1 Since no stock of l2 is available and no other luteus mutants are located on chromosome 10L this mutant

of segregation states that diploid organisms inherit two genes per trait and each gene segregates from the other during meiosis such that each gamete will receive only one gene per trait Testcrosses In a testcross an individual that shows a dominant phenotype is crossed with individual with a recessive phenotype Examining the offspring allows you to determine the
