Which of the following groups of scientists were influential around
the year 1900 in setting the stage for our present understanding of
C) deVries, Correns, Tschermak, Sutton, Boveri
Name the single individual whose work in the mid-1800s contributed to
our understanding of the particulate nature of inheritance as well as
the basic genetic transmission patterns. With what organism did this
E) Boris Ephrussi; Ephestia
A) Gregor Mendel; Pisum sativum
A recessive allele in tigers causes the white tiger. If two normally
pigmented tigers are mated and produce a white offspring, what
percentage of their remaining offspring would be expected to have
Polydactyly is expressed when an individual has extra fingers and/or
toes. Assume that a man with six fingers on each hand and six toes on
each foot marries a woman with a normal number of digits. Having extra
digits is caused by a dominant allele. The couple has a son with
normal hands and feet, but the couple's second child has extra digits.
What is the probability that their next child will have
Tightly curled or wooly hair is caused by a dominant gene in humans.
If a heterozygous curly-haired person marries a person with straight
hair, what percentage of their offspring would be expected to have
B) 50% straight
Which types of phenotypic ratios are likely to occur in crosses when
dealing with a single gene pair for which all the genotypic
combinations are of equal viability?
B) 1:2:1, 3:1
Assume that a black guinea pig crossed with an albino guinea pig
produced 5 black offspring. When the albino was crossed with a second
black guinea pig, 4 black and 3 albino offspring were produced. What
genetic explanation would apply to these data?
D) albino = recessive; black = dominant
The fundamental Mendelian process that involves the separation of
contrasting genetic elements at the same locus would be called
The Chi-square test involves a statistical comparison between
measured (observed) and predicted (expected) values. One generally
determines degrees of freedom as ________.
B) one less than the number of classes being compared
