How do mice lose their tails?
Mice should not loose their tails. If they do, than an animal harmed it or the tail got stuck. Mice do not drop their tails like lizards, and mice are mamals, all mamals do not loose their tails
Who disproved Lamarck's theory of use and disuse?
If I'm not mistaken the Law of Use and Disuse was disproved by August Weisman (scientist) several years after the death of Darwin (late 1800's). Weisman thought that if the law of use and disuse was true, he could prove it by cutting off the tails of mice for 20 generations in a row. No matter how many mice he cut the tail off of, the babies were born with a tail. His experiment proved that the law of use and disuse was false.
Can cutting of the tails of mice for 100 generations result in a strain of mice with genes for short tails?
The length of the mouse tails are determined by their genes. If a mouse has a 6cm tail, then cutting the tail off will not affect the mouse's genes, you've only modified the mouse on a cosmetic level, not a genetic one. That mouse's genes still contain the 'blueprints' for that 6cm tail, and it is these it will pass on to offspring. It doesn't matter how many generations you do it for, you cannot change their genetic makeup like this. What you need to do is use artificial selection. Because of how genes work, there is variation amongst a species. These traits are what are passed on to offspring. You could take the mice with the shortest tails, and breed them together, then from their offspring, again breed the shortest tails together, and disallow the longer tailed ones from breeding. Eventually the average tail length of that group will become smaller, as more mice are passing on 'small tail' genes.
