Genetic Linkage

Recombination Occurs Less Frequently Between Closely Linked Genes

• Physical crossing over is a normal meiosis event
• The term used to describe crossing over is recombination
• Recombination can occur between any two genes on a chromosome
• The farther apart the two genes the more crossing over

• If genes are far enough apart the number of cross over gametes will equal the number of parental gametes

• The parental arrangement determines which gametes will be parental and which will be recombinant
