Two genes are on the same chromosome, yet crossing over occurs between them every time meiosis occurs. Are these
genes linked or unlinked and why?
What will be an ideal response?
ANSWER: Unlinked. The definition of linkage is when two genes do not assort independently. If
crossing over occurs between two genes every time meiosis occurs, these genes will always
assort independently.
