Sex Chromosomes vs. Autosomes
• Humans have 23 pairs of chromosomes (23 from mom, 23
from dad) or a total of 46
• 22 of these chromosomes are known as “autosomes” (nonsex chromosomes). These are the same for all males and
females.
• The last pair of chromosomes (pair #23) are known as “sex
chromosomes” because they are specific to males and
females
• Males inherit an X chromosome from mom and a Y
chromosome from dad (XY)
• Females inherit an X chromosome from mom and another X
chromosome from dad (XX)
• So which gender actually determines the gender of a child?
Punnett Square for “sex-linked”
inheritance patterns
• Color blindness is a recessive disorder that affects
the X chromosome. If a normal man marries a
woman who is a carrier...
1) What are the chances they will have a son with
color blindness?
2) What are the chances they will have a daughter
with color blindness?
• We can use the same four step process for genetics
problems!
