The Avenue des Champs-ElysÃ©es is probably the most famous avenue in the world. This impressive street stretches from the Place the la Concorde to the Place Charles de Gaulle, the site of the Arc de Triomphe.
Best Answer: Crossing-over is another name for recombination or physical exchange of equal pieces of adjacent non-sister chromatids. When crossing-over occurs chromatids break and may be reattached to a different homologous chromosome.
If crossing over didn't happen during meiosis in humans, the haploid daughter cells would all have the same genes. The crossing over creates variation and causes each daughterâ¦ cell to have slightly different genes.
