true
false
What does 10 centiMorgans (cM) repre-
sent?
a.10% recombination between two
genes on different chromosomes
b. 10% recombination between two
genes on the same chromosome
c. 1% recombination between two genes
on different chromosomes
d. 1% recombination between two genes
on the same chromosome
In a dihybrid test cross of two linked
genes, the frequency of the parental
phenotypes in the offspring is always
______ the frequency of the recombi-
nant phenotypes of offspring. (Fill in the
blank)
a. greater than
b. similar to
c. less than
Syntenic genes are:
A. located on the same chromosome
B. found in different species
located on different chromosomes
C. located far from one another on the
same chromosome
D. located near one another on the same
chromosome

We have three genes: A, B, and C. The
distance between A and B is 20 cM, the
distance between B and C is 10 cM,
and the distance between A and C is
30 cM. The recombination rate is highest
between genes:
A. A and C

all three pairs
D. B and C

genes in cM?

b. 15
c. 20
d. 0.38
e. 100
