A mother and father both have brown eyes, but their child has blue eyes. Which statement most likely explains this

Blue eyes is a recessive trait

Explanation:

Recessive traits show in 25% of the offspring, but they skip the first generation. This means that the 25% only shows up in the second generation unless two recessive traits are put together. A likely combination is that both of the parents had Bb, which you can put into a punnet square to visualize.

      B       b

B    BB     Bb

b    Bb     bb90

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).
