Question

Why don't alleles from linked genes assort independently, if no crossing over occurs? Crossing over is random, so the closer genes are on the chromosome, the less likely crossing over is to occur. They end up on different chromosomes, so are then transmitted independently of each other. They are transmitted together (on the same chromosome), instead of being transmitted independently of each other. They are involved in the same traits, so are transmitted together.

Explanation / Answer

Q1- Option 3 is correct

Since there is not crossing over, they will stay on the same chromosome. Thus no chance of independent assortment

Q2- Option 3 is correct.

Due to crossing over, if the genes are linked but the distance is more between them, then they end up on different chromosom and thus transmitted independently.
