Two dominant non-allelic genes are 50 map units apart.The linkage is

A

cis type

B

trans type

C

complete

D

absent/incomplete

Text Solution

Verified by Experts

The correct Answer is:
D
Chromosome mapping is based on two genetic principles
(a) The frequency of crossing over between two genes is directly proportional to the distance between them in the chromosome.
(b) Genes are arranged in a linear order in the chromosome.
50 map unit distance between the genes is quite enough to change the cis arrangement of dominant genes into trans. So, there is no fixed linkage present.
