A cell undergoes meiosis. How do the gametes it produces compare with the original cell and with one another? a. The gametes are genetically identical with the parent cell and with one another.
b. The gametes have half the chromosomes of the parent cell, and are genetically identical with one another.
c. The gametes have half the chromosomes of the parent cell, and are genetically different from one another.
d. The gametes have one fourth of the chromosomes of the parent cell, and are genetically identical with one another.

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects

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).
