The phenotype of an animal typically does not depend on a) the genotypes of the parents. b) seasonal changes in the environment. c) the source of the animal's food. d) how genes of the animal are expressed.

The correct answer is-

C) The source of the animal's food.

Phenotype of an organism can be described as the physical characteristics or traits that the individual possesses ( such as hair color, eye color, skin color).

It is depicted by the genetic makeup ( that is genes) of the organism that is inherited from parents and is also influenced by some environmental factors.

Thus, it does not depend on the source of the animal's food.

Therefore, option C) is the right answer.

the tricuspid valve is present between right atrium and right ventricle

ans.

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.'
