Answer:
Option B, A population for which p+q = 1 and p2 + 2pq + q2 = 1
Explanation:
As per Hardy Weinberg's first equation, the sum of probability of occurrence of two allele at the locus is equal to one.
Floppy has two genes i.e F and f and f(F) = p and f(f) = q then

As per Hardy Weinberg's second equation

which shows that
Frequency of occurence of genotype FF is a given population is 
Frequency of occurence of genotype ff is a given population is 
Frequency of occurence of genotype FF is a given population is 
PROTANOPE. These are the individuals that suffers form color blindness. This color blindness is due to the absence fo the L- cones which are cones that are sensitive to long wavelength. Cones are one of the three types of photoreceptos found in the retina. These are responsilble for color vision and function best in a brightl light. In contrast to the rods which works on dim light. Cones are found in the fovea.
Answer:
A. Scientists include their research methods because other scientists need to repeat the tests and confirm their results.
Explanation:
I would say A sounds the most convincing out of all listed
