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.
What else can I help you with?
Does cutting a tail to an animal result in shorter tails after several generations?
no because it is not a part of their genes. if they selectively breeded the dogs with the shortes tails then it would start becoming shorter in future generations, but they just cut the tail off short no matter how long or short the tail is
New inherited characteristics may appear in offspring as a result of new combinations of existing genes or may result from mutations in genes comtained in cells produced by structure?
That's correct! New inherited characteristics in offspring can result from new combinations of existing genes during meiosis, leading to genetic variation. Mutations in genes can also occur, creating new genetic traits that can be passed down to future generations.
What is transformation in DNA?
transformation is the process in which one strain of bacteria is changed by a gene or genes from another strain of bacteria

How can science prevent implanted genes from being passed on to the next generation?
Only by not implanting the genes in the first place. Once implanted, the genes will be passed on to future generations. If the implanted genes corrects a medical defect and future generations don't suffer from the same defect, then implanting genes could be classed as a benefit to mankind.
A disease caused by mutated recessive genes that can be passed along for generations with no expression is?
cystic fibrosis
