How did your results change as the number of trials you completed increased? Why was it important for you to breed the chickens repeatedly in this experiment?

Due to change in genetic combination.

Explanation:

The results change as the number of trials increased because variation occur in the genetic combinations of chickens. It is important to breed the chickens repeatedly in this experiment in order to gain accuracy and attain best results. If the chicken is breed repeatedly, at the beginning changes occur in their offspring due to change in their genetic makeup so for accurate results repetition is necessary.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
