4-11-16 - WEEKLY REFLECTION
This week, we learned about sex-linked genes or traits that are inherited through gametes (sex cells). Sex-linked genes can be x-linked or y-linked, and the possibility of inheritance depends on the gender of the individual and the traits of their parents. Males have an X and Y chromosome, and so if they inherit an x-linked trait, they will still exhibit that trait, regardless of the fact if it is dominant or recessive. Meanwhile, females have both X chromosomes, therefore the x-linked trait has something to compare it to, and it is possible that they will not carry the trait or are merely carriers. Both men and women can inherit x-linked traits since they both have an X chromosome. An example of an X-linked trait is haemophilia. Y-linked traits are traits carried in the Y chromosome, and only males can inherit it.
