Answer:
Genotype of Parent 1: Aa

Probability of offspring having freckles: 50%
Explanation:
The genotypes of the parents are actually given in the Punnett Square. And, since out of 4 options 2 are all freckles, probability is 50%.
The answer is C) The fluorescent cells can help track the movement of cells.
Explanation:
Fluorescent animals such as rabbits have been created by using the GFP gene that is the Green Fluorescent Protein, which occurs naturally in the Aequorea Victoria jellyfish. In this way, the protein was extracted from jellyfish and used in mammals, including rabbits. This particular use of genetics does not only make animals glow in the dark but also helps geneticists to study cells as it makes visible how cells move, develop or change. Thus, the correct answer is C.
