Which statement is true about crossing over of genes?

Crossing over does not occur between genes that are far apart from each other on a chromosome.

Frequency of crossing over is related to the distance between linked genes.

Genes that are close to each other frequently cross over.

Answer: Option B

Explanation: Crossing over can be defined as the exchange of genetic material between the two homologous non sister chromatid.

This results in the recombination of chromosomes during sexual reproduction. The frequency of crossing is linked by the distance between two genes.

If the chromosomes are far then chances of crossing over is more and if the distance between the genes are less then then the chances of crossing over is less.

B is the correct answer Crossing over does not occur between genes
