Answer the following statements true (T) or false (F)
1) If the p value corresponding to a given ?2 value and number of degrees of freedom is lower than 0.05, then the null hypothesis is rejected and it can be said with some confidence that the two genes being evaluated are linked. 2) Genes that are not syntenic are not linked. 3) The genetic distance from one end of a linkage group and the other may exceed 50 m.u. because the distances between many gene pairs are added together to make the map. 4) Sectors with a different phenotype in an otherwise uniform yeast colony may be evidence of mitotic recombination. 5) Large sectors suggest a mitotic recombination event late in the growth of a yeast colony. 6) A coefficient of coincidence of 0.5 in a region of three genes means that half as many double crossovers were observed as would have been expected if crossovers in the two intervals were independent.
