Draw a Punnett square. cross an XX woman with an XY man.
How many kinds of eggs can a woman produce in terms of their sex chromosomes?
How many kinds of sperm cells can men produce in terms of their sex chromosomes?
In any given fertilization event, what is the chance that a child will be XX? XY?
In any given fertilization event, what is the chance that a child will be male? Female?

male or female.
Remember that since most sex-linked traits are recessive, the person wno
shows the trait can have no X's with big superscripted letters. So, y a male
carries the trait, he must also show the trait.

Guided Questions:
1. What chromosomes will result to a normal phenotype (normal spongy pore
trait)?
2. Do all individuals who have the spongy tiny pore allele show it in their physical
appearance? Why or why not?
3. Can males be a carrier of an X-linked recessive trait? How about females?
Explain.
4. What will be the sex of an individual who is easily affected by an X-linked
recessive trait? Why?.
The Y chromosome is missing this section
of the X chromosome. The lower sections
Males are at greater risk for inheriting
Explain comprehensively.
a. How does evolution play a role in meiosis and sexual reproduction?
b. Explain the importance of meiosis in spermatogenesis
