Show transcribed image text Ypu are studying three genes in snails that are linked. Each of the 3 genes has either of two possible alleles: a dominant allele or a recessive allele (r = right spiral shell, R = left spiral shell; t = twisted tail, T = regular tail; b = brown color, B = black color). A snail that is homozygous wild-type for all the genes is mated to a snail that is homozygous recessive for all genes. The resulting F1 progeny were test-crossed and the following progeny were produced from the test-cross: Determine the linear order of the genes on the chromosome and how do you know this? Calculate the recombinant distances between the three loci. Determine the coefficient of coincidence for these three loci.
