C. easily identifiable traits
D. easy to grow

B

Explanation:

(Reason for the selection of pea plants for the genetic experiments

The reason for the selection of pea plants for the genetic experiments are

Easy to grow in the garden.

The flowers of pea plants are hermaphrodite, i.e flowers have bisexual characteristics.

Easy to obtain pure breed plant through self-fertilization

The generation time of pea plants is less.

They have excellent disease resistance and have an optimal rate of survival.

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.'
