Biology for IGCSE & O level - Inheritance (Section 12 - No. 4)
If two genes are located close together on the same chromosome, what is their relationship?
They are linked.
They will always assort independently.
They are on different chromosomes.
The probability of crossing over between them is low.
Explication
Genes close together tend to be inherited together (linked). The closer they are, the lower the chance of crossing over occurring.
