PATHOLOGY

Detailed explanation-1: -Explanation: Crossing over is a process that happens between homologous chromosomes in order to increase genetic diversity. During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material.

Detailed explanation-2: -Crossing Over This process results in new combinations of alleles in the gametes (egg or sperm) formed, which ensures genomic variation in any offspring produced.

Detailed explanation-3: -Crossing-over increases genetic variation by creating different chromosomes in offspring in comparison with their parents. The amount of genetic variation in a population is important because natural selection is dependent upon varying alleles to increase or decrease their frequencies.
