Question

The percentage of crossing-over between 4 linked genes (K, L, M, N) are below. Put them in the correct sequence.

Between M and N: 8%

Between K and N: 5%

Between K and L: 16 %

Between N and L: 11%

Between M and L: 19%

Answer 1

NL=8, JK=2, KL=2, LM=2

Explanation:

K is between J and M

JM=JK+KM

JM=KL+KM

JM=2+4

JM=6

The length of JM is 6 units.

From the figure it is clear that

MN=JN-JM

MN=14-6

MN=8

From the figure it is clear that

NL=ML+MN

NL=2+8

NL=10
