Chromosome mapping Determine the sequence of the genes below. A – B = 34 C – B = 19 A – C = 15

Chromosome mapping The following distances are determined for several gene pairs. Determine the sequence of these genes. What is the distance between k and m? j – k = 12 j – m = 9 k – l = 6 l – m = 15

The sequence is k l j m or m j l k and the distance between k and m is 21 map units.

The following recombination frequencies were determined The following recombination frequencies were determined. What is the order of these genes on the chromosome? a – c = 10; a – d = 30; a – e = 6; b – c = 4 b – d = 16; b – e = 20; c – d = 20 What is the distance between a and b?

The order is e a c b d and the distance between a and b is 14.

a. Determine the sequence of the genes below. b. What is the distance between c and d? a – b = 8; a – c = 28; a – d = 25; b – c = 20; b – d = 33

d a b c is the order. 53 map units apart.

Determine the sequence of the following genes: P – Q = 17 S – T = 9 P – T = 12 P – S = 3 S – Q = 14 What is the distance between T and Q?
