What is the difference between a linkage map and a physical map?

#Unit 11. Evolution and Behavior

  1. For a linkage map, markers are spaced by recombination frequency, whereas for a physical map they are spaced by numbers of base pairs (bp).

  2. For a physical map, the ATCG order and sequence must be achieved, but not for the linkage map.

  3. For a linkage map, it is shown how each gene is linked to every other gene.

  4. For a physical map, the distances must be calculable in units such as nanometers.

How can evolution select for phenotypes that postpone reproduction or sexual maturity?” There is often a trade-off between reproduction and maintenance, and in many species reproduction and senescence are closely linked. Recent studies of mice, Caenorhabditis elegans, and Drosophila suggest that there is a conserved genetic pathway that regulates aging and that it can indeed be selected for. This pathway involves the response to insulin and insulin-like growth factors, Name of these transcription factors are
