Answer:
cloning
Explanation:
one of the most controversial uses of genetic engineering has been cloning, or producing a genetically identical copy of organism. while the ethics of cloning are hotly debated, the 1st ever sheep was cloned in 1996 by scientists. 
 
        
             
        
        
        
Answer:
3 long tails : 1 short tail
Explanation:
This question involves a single gene coding for tail length in mice. The allele for long tail (T) is dominant over the allele for short tail (t). This means that an heterozygous mice will possess the long tail length. 
According to this question, in a cross between two hybrid or heterozygote mice i.e. Tt × Tt, the following gametes will be produced by each parent:
Tt - T and t
Using these gametes in a punnet square (see attached image), the following will be produced: TT, Tt, Tt and tt.
Offsprings with genotype TT, Tt and Tt will have a LONG TAIL while genotype  tt will have a SHORT TAIL. Hence, the phenotypic ratio will be 3 long tails : 1 short tail.

This is possible by having different stem cells for different types of cells which then have different genes activated to make cells different
