Is this correct? Can someone please correct my work? In a population of Biology instructors, 250 out of 1000 have a receding hairline; the rest do not.
Assume that having a receding hairline is completely recessive and is controlled by a single genetic locus. Calculate the following:
A. The allele frequencies of each allele.
Receding = P = 25%
Non-receding = Q = 75%
B. The expected genotype frequencies.
P^2 = 57%
Q^2 = 6%
C. The number of heterozygous individuals that you would predict to be in this population.
37% = heterozygous
Is this correct?

Which of the following statements is a scientific claim? a. the early solar system had large amounts of water; so, the oldest objects in the solar system should also be abundant in water. b. earth is shaped like a sphere even if not all of the scientific observations related to its shape support this idea. c. the mass of the universe is much greater than current models predict; it is not possible to explain this inconsistency. d. planet earth is abundant in water, but there is no way to scientifically determine from where earth's water originated.
