Answer: The correct answer is-
B. Yy
As per the information in the question, yellow (depicted by Y allele) seed color is a dominant trait whereas green seed color is a recessive trait ( depicted by y allele).
A dominant trait always masks the expression of a recessive trait.
Presence of single dominant allele ( such as in Yy, which shows heterozygous dominant genotype) in the genotype can produce a dominant trait whereas recessive trait is only expressed when its genotype is homozygous recessive (such as yy that is both alleles should be recessive allele) .
A plant with genotype Yy will form two gametes that is Y and y.
When such plants are allowed to interbreed, there is a probability of 25% of producing green seeds in the next generation.

Answer:
C. The North Atlantic Gyre flows in a clockwise direction, so the prevailing current on the Florida coast would be south to north, and it would disperse lionfish up the coast.
Explanation:
See the attached picture. The current that is most likely to act on lionfish near Florida would move from south to north.
