How does crossing over affect linked genes?
Crossing over during meiosis can separate linked genes, leading to genetic recombination and producing recombinant offspring.
Recombinant offspring are those with different allele combinations than their parents as a result of this crossing over.

What is the role of chiasmata in linkage?
Chiasmata are regions where crossing over occurs, potentially separating linked genes.

Why are closely located genes more likely to be linked?
Genes closer together are more likely to be linked as they have a lower chance of being separated by crossing over.
Closer genes therefore produce fewer recombinants as they're less likely to be separated.

Can linked genes assort independently?
No, linked genes do not undergo independent assortment unless they are separated by crossing over.
