(a) Give the genotypes of the two parental goats, showing gene arrangement and gene order.
(b) Give the % recombination between each pair of genes.
(c) Draw a map showing the positions of all genes and distances between genes, where appropriate
(d) Give the formula and calculate the coefficient of coincidence
(e) Calculate interference.
2. Given the map a 10 b 20 d , and with no chromosome interference, how may phenotypically a+b+d individuals would you expect in a progeny of 1000 of the following cross:
a+ b d+ / a b+ d X a b d / a b d ?
