Question

Heterozygous genetic screening is used mainly to

a. detect genetic disorders among newborn infants.
b. detect adult members of a particular population who may be heterozygous carriers for recessive disorders.
c. detect in healthy adults the presence of a mutant allele that may predispose them to some serious health problem later in life.
d. detect fetuses who may be heterozygous carriers for recessive disorders and may eventually be at risk of having children of their own with these disorders.
e. detect adults that may be heterozygous for serious autosomal dominant disorders.

Answer 1

Heterozygous genetic screening is mainly used to detect adult carriers of recessive disorders.

Step-by-step explanation:

Heterozygous genetic screening is mainly used to detect adult members of a particular population who may be heterozygous carriers for recessive disorders. By identifying individuals who carry a single copy of a recessive gene, healthcare providers can provide appropriate counseling and preventive measures to minimize the risk of transmitting these disorders to their offspring.
