1
.

2.
Why are sex
-
linked
traits more common in males than females?

linked recessive traits are expressed by inheriting only one recessive

gene.


b.
Males have two X chromosomes, and sex
-
linked recessive traits are expressed by
inheriting only one recessive
gene.


c.
Females have two X chromosomes, and sex
-
linked recessive traits are expressed by inheriting only one recessive
gene.


d.
Females have only one X chromosome, and sex
-
linked recessive traits are expressed by inheriting

only one
recessive gene.

8.
This pedigree represents the ability to ro
ll one’s tongue in three generations of a family. Tongue rolling is inherited
as a dominant autosomal allele. Individual III

9.
This pedigree represents hemophilia in four generations of a family. Which statement
best

explains how individual
IV
-
9 inherited hemophilia?




a.
A spontaneous mutation occurred producing hemophilia.


b.
The
allele for hemophilia was inherited on the Y
-
chromosome.

c.
Hemophilia was inherited as a recessive allele from the father, who must be heterozygous for the trait.

d.
The recessive allele for hemophilia was inherited on the X
-
chromosome from the mother, wh
o must be a carrier.
