traits,
2. Students will demonstrate an understanding of
sex-linked traits and their inheritance patterns,
3. foster an appreciation for the complexity of sex-

16. 1. Which of the following statements best defines
sex-linked inheritance?

and Y chromosomes.

males.
C. The passing on of genes that are located on the
autosomal chromosomes.

a result of sex-linked inheritance?

18. 3. Which of the following traits is
an example of sex-linked
inheritance?

B. Height D. Color blindness

19. 4. In humans, which chromosome carries
most of the genes responsible for sex-
linked traits?
A. Chromosome 1 C. X chromosome
B. Chromosome 7 D. Y chromosome

20. 5. Color blindness is an example of an
X-linked trait. Who are the possible carriers of
the color-blindness trait?
A. Men who are homozygous for the trait

21. MELC 3: Explain the different patterns of non-Mendelian Inheritance.
S9LT-Id-29
OBJECTIVES:
1. define sex-linked, sex-limited, and sex-influenced traits, provide
examples of each, and understand how these traits are inherited.
2. solve genetic problems related to sex linked, sex-limited, and sex
influenced traits using Punnett square.
3. Promote open-mindedness and respect for individuals with sex-limited
traits, ensuring a positive and inclusive learning environment.

22. 1. What are sex-linked traits?
A. Traits determined by multiple genes
B. Traits controlled by environmental
factors
C. Traits located on sex chromosomes
D. Traits influenced only by the mother's
genes

23. 2. Hemophilia, a disorder that
affects blood clotting, is an
example of a sex-linked trait.
Which chromosome is involved in
this condition?
A. X B. Y C. Z D. W

24. 3. What are sex-limited traits?
A. Traits that are only expressed in one sex
B. Traits that are expressed in both sexes
equally
C. Traits controlled by multiple genes
D. Traits influenced by environmental factors

25. 4. In humans, male pattern baldness is a sex-influenced
trait. It is associated with a dominant allele (B) for hair

C. Traits that are influenced by hormones and are
more prevalent in one sex
D. Traits that are controlled by multiple genes
