Principle Of Inheritance And Variation Question 119
Question: The map distance between genes A and B is 3 units, between B and C 10 units and between C and A 7 units. The order of the genes in a linkage map constructed on the above data would perhaps be [CMC Vellore 1994]
Options:
A) A, B, C
B) A, C, B
C) B, C, A
D) B, A, C
Show Answer
Answer:
Correct Answer: D
Solution:
From the recombination frequencies between different genes A, B and C, it is clear that distance between A and B genes is 3 units, between B and C 10 units and C and A 7 units.
Hence linear order of genes on chromosomes is:
