When it comes to sex-linked traits, there are some common myths that people believe. Let’s break them down:
Equal Impact on Both Sexes:
Many people think that sex-linked traits affect boys and girls the same way.
But that's not true! Traits that are on the X chromosome usually affect boys more often.
For example, color blindness happens in about 8% of boys, while only about 0.5% of girls are affected.
Confusion About Inheritance:
Some believe that these traits can skip generations.
But here's the truth: if a trait is recessive, it can show up in future generations.
For instance, if a mother carries the gene for a trait, there’s a 50% chance that her sons will have that trait.
Misunderstanding Dominance:
A lot of people think that all sex-linked traits are recessive.
That's not the case! Some traits are actually dominant.
A good example is a condition called X-linked hypophosphatemia.
By understanding these points, we can clear up some confusion about how sex-linked traits work!
