- What does this boy want?
- Doc! Doc! Doc!
- Wow, Dean, that's quite the announcement.
- Doc, I just found out I have Hemophilia!
- Well, none of that really matters Dean, Because Hemophilia is a sex-linked inheritance
- I don't understand Doc! I'm active. I eat my vegetables. I'm young. How do I have this sickness
- Yes, Sex-linked, aka x-linked. Which causes inheritance of a certain trait to a certain gender. These alleles are found on x or y chromosome. In your case its found on the x chromosome and you most likely inherited the hemophilia gene from your mother.
- Sex-linked Inheritance?
- Well, if you're thinking autosomal inheritance, your wrong, this inheritance is when the certain allele is found on the autosome (non-sex) chromosomes.
- You sure it was from my mom? Maybe it was just a DNA mixup.
- Sorry, Dean, But you definitely inherited the Hemophilia allele from your mom. When you get home try making a pedigree to track the heritance pattern, check out my link to my infographic and it'll explain everything bud.
- Alright, Doc, Thanks for filling me in on this information. I'm gonna be having a talk with my mom when I get home.
