A scientist discovers a DNA-based test for one allele of a particular gene. This and only this allele, if homozygous, produces an effect that results in death at or about the time of birth. Which of the following statements describes the best use of this discovery?
a. Screen all newborns of an at-risk population.
b. Design a test for identifying heterozygous carriers of the allele.
c. Follow the segregation of the allele during meiosis.
d. Introduce a normal allele into deficient newborns.

Screen all newborns of an at-risk population.

Explanation:

When all newborns are screened, it enable the researcher to identify areas with lapses   in order to correct such either by introducing an heterozygous to correct the abnormality

the answer is d (apex) good luck : ))

colors do exist. the color of the sky is actually violet; humans percieve the color of the sky as blue.
