Crossing over brings:
Correct answer: A. Recombination of genes
- A. Recombination of genes
- B. New trait into species
- C. Reduction in number of chromosomes
- D. Segregation of genes
Explanation
Is correct as In genetics, the term "crossing over" refers to the exchange of genetic material between homologous chromosomes that occurs during meiosis. This process plays an important role in generating genetic diversity, as it can create new combinations of alleles on each chromosome. During crossing over, the chromatids of two homologous chromosomes pair up and exchange corresponding segments of DNA. This results in a mixing of genetic material, as some of the alleles on each chromosome are replaced with new alleles from the other chromosome.

About Gene Linkage and Crossing Over
Linked genes lie on the same chromosome and tend to pass together, unlike genes that assort independently on different chromosomes. The topic connects linkage with homologous pairing, crossing over during prophase I of meiosis, recombinant and parental offspring, and recombination frequency as an estimate of gene distance.
