16. A student is using a straw to blow bubbles into a calcium hydroxide solution. The carbon dioxide in the student's breath is reacting with the water to form an acid, which
begins to neutralize the basic solution. Which of the following best describes the initial
change in pH of the solution?
A. increase in pH toward a pH of 7
B. increase in pH away from a pH of 7
C. decrease in pH toward a pH of 7
D. decrease in pH away from a pH of 7

It's true...

Explanation:

Under the light of Mendel's laws of segregation and independent assortment, the ratio of the hetrozygous alleles always remain constant no matter what the circumstances are.

In the case of a dominant allele, it is very easy to be selected even when joined with a recessive part because that's the way of nature and in hetereozygous condition only the dominant phenotype appears and recessive expression gets masks din the process. It means it requires only one dominant parent to be major in the population. However, in the case of recessive allele, it's phenotype only appears when both of the parent recessive alleles are equally participating. That's why the recessive population is very low due to less rational selection.
