Homologous recombination occurs wherever there are long regions of the same or similar nucleotide sequence in two dna molecules.
<h3>What is The role of recombination?</h3>
Long jumps through a broad genotype space are caused by recombination. Recombination can substantially facilitate the investigation of novel phenotypes because different portions of this space include distinct novel phenotypes. However, these big jumps frequently ruin a parental, well-adapted genotype. This is a fundamental issue in understanding the role of recombination in evolutionary innovation.
These details demonstrate that the problem is far less serious than one might anticipate based on data from proteins and regulatory circuits. First, because it exchanges system pieces that are consistent with a given phenotype, recombination has far smaller impacts than mutation. Second, previous recombination exposure of a system can greatly boost the system's recombination robustness. It may result in the preservation of the great majority of recombinants

Answer: Each air sac is surrounded by a network of fine blood vessels (capillaries). The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell.
In my own words
Each air sac is encircled by an organization of fine veins (vessels). The oxygen in breathed in air goes over the slim coating of the air sacs and into the veins. This is known as dissemination. The oxygen in the blood is then hefted around the body in the circulation system, arriving at each cell.
