I only get two tries to get both correct and I already used one of them. Recombination frequencies a.) decrease with distance. b.) arise from completely random genetic exchange. c.) are the same for all genes. d.) are the same for cis and trans heterozygotes. Compared to a two-point testcross a three point testcross a.) is more accurate. b.) is less accurate. c.) is equally accurate. d.) is possible only in yeast. e.) measures different things. Any help would be greatly appreciated.
