UPDATED ACTUAL QUESTIONS AND CORRECT
ANSWERS
◉ Gilford observed young children with symptoms of old age and
called it.
Answer: progeria, derived from the Greek word for "prematurely
old"
◉ Hutchinson-Gilford syndrome is also known as.
Answer: HGPS
◉ Children with HGPS appear healthy at birth but, by 2 years of age,
usually begin to show features of.
Answer: accelerated aging, including cessation of growth, hair loss,
aged skin, stiffness of joints, heart disease, and osteoporosis.
◉ By the age of 13, those who have HGPS, have died, usually from.
Answer: coronary artery disease
◉ HGPS is usually inherited as a.
Answer: autosomal dominant trait
,◉ Gordon and Berns.
Answer: established the Progeria Research Foundation
◉ Gordon focused her career on.
Answer: directing the foundation and conducting research on HGPS
◉ HGPS results from mutations in a gene called ______ which is
located on human chromome 1.
Answer: lamin A (LMNA)
◉ The specific mutations that cause HGPS produce an abnormal,
truncated form of the lamin A protein, which.
Answer: disrupts the nuclear membrane and in some unknown way,
results in premature aging.
◉ The _____ of the nucleus may play a role in normal aging.
Answer: architecture
◉ Three important techniques used by geneticists to investigate
certain characteristics.
Answer: pedigree, twin studies, and adoption studies.
,◉ Many important characteristics are influenced by.
Answer: both genes and environment
◉ Studies of twins and adopted persons are designed to.
Answer: distinguish the effects of genes and environment such
studies are based on assumptions that may be difficult to meet for
some human characteristics, particularly behavioral ones.
◉ ______ are the best and the worst of all organisms for genetic study.
Answer: Humans

Answer: not possible
◉ Another genetic testing obstacle is that humans have a ____
generation time.
Answer: long

wait on average _____ just to observe the F2 progeny.
, Answer: 40 years

not permit the recognition of a.
Answer: dihybrid 9:3:3:1
◉ An important technique used by geneticists to study human
inheritance is the analysis of.
Answer: Pedigrees
◉ A pedigree is.
Answer: a pictorial representation of a family history essentially a
family tree that outlines the inheritance of one or more
characteristics
