How can crossing over lead to the expression Of new traits

Crossing over, or recombination, is the exchange of chromosome segments between nonsister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.

What is Crossing over?

Crossing over, or recombination, is the exchange of chromosome segments between non-sister chromatids in meiosis.
Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.

How can crossing over lead to the expression of new traits?

During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material.
Gametes gain the ability to be genetically different from their neighboring gametes after crossing over occurs.
Due to crossing over, the genetic recombination, the offspring have a different set of alleles and genes than their parents do.
