What is the difference between dominant and recessive traits

Dominant trait is the trait which is expressed in the F1 generation and in the next generations. The characters that is expressed in the phenotype is known as dominant.

The characters which is not expressed in the F1 generation is known as recessive characteristics.

If a cross is made between the Tall (TT) and short plant (tt) then the F1 generation will have all the four plants as tall plant (Tt).

In this case the dominant trait is tallness and the dwarfness is recessive trait.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
