Question

Explain the relationship between crossing over and genetic variation.

Answer 1

Crossing over is the process by which genetic material is exchanged by non-sister chromatids during meiosis.

Crossing over results in a new combination of genetic information for the cell for a specific trait.

Crossing over ensures that organisms are not identical from generation to generation.

Genetic recombination allows for a variation in genetic material that is passed through the generations

Answer 2

Crossing over leads to genetic variation.

Crossing over is the process during meiosis during which homologous pairs of chromosomes exchange genes, giving rise to new combinations of genes within the chromosomes. This is an important source of genetic variation.
