MourningBands added 2 new photos. Honoring Those that Answered the Call. When people answer the call of public service with their lives, as far as I'm concerned, that's the gold standard. That was my thought when I brought these pieces together, and my thought each and every time one of them falls in the line of duty.
Best Answer: A mutation is a change in DNA. Genetic recombination can apply to two things: crossing-over between homologous chromosomes or recombining of traits when gametes fuse during fertilization. They all contribute to evolution because they result in a new organism with a new combination of characteristics. This new combination of characteristics is subjected to natural selection.
recombination. Recombination in meiosis. Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles. This recombination process creates genetic diversity at the level of genes that reflects differences in the DNA sequences of different organisms.In eukaryotic cells, which are cells with a nucleus and organelles, recombination typically occurs during meiosis.Meiosis is a form of cell division that produces gametes, or egg and sperm cells. During the first phase of meiosis, the homologous pairs of maternal and paternal chromosomes align.n eukaryotic cells, which are cells with a nucleus and organelles, recombination typically occurs during meiosis.
