Question

Linked gene are separated by

• A. Crossing over
• B. Mutation
• C. Both A and B
• D. Mitosis

Answer 1

The correct option is A Crossing over

Recombination can occur between any two genes on a chromosome, the amount of crossing over is a function of how close the genes are to each other on the chromosome. If two genes are far apart, for example at opposite ends of the chromosome, crossover and non-crossover events will occur in equal frequency. Genes that are closer together undergo fewer crossing over events and non-crossover gametes will exceed than the number of crossover gametes.
