Question

For each of the following traits, indicate if we could learn if each of the following perinatal tests we’ve learned about (genetic carrier testing, pre-implantation genetic diagnosis (PGD), non-invasive pre-natal testing (NIPT), and newborn genetic screening) would be “informative,” “not informative,” or “not necessary.”. If a test could possibly be used to detect it, but isn’t necessary, explain why.

a) Allergies (complex trait with genetic and environmental components)

b) Albinism (total lack of pigmentation, a simple recessive genetic trait with known genetic basis)

c) Unattached earlobes (a simple dominant genetic trait, the gene that controls the trait is unknown)

d) Jacobs syndrome (where an individual has sex chromosomes XYY, there are no severe symptoms of this genetic condition) e) Double eyelashes (simple dominant trait) caused by a novel mutation in one of the meiosis that created one of the gametes that made this baby.

Answer 1

A) ans= allergies= genetic carrier testing will be INFORMATIVE.

B) ans= Albinism= NIPT & Genetic carrier testing will be INFORMATIVE.

C) ans= attached earlobe= NOT NECESSARY

D) ans= Jacobs syndrome= NIPT INFORMATIVE

E) Double Eyelashes= NIPT INFORMATIVE
