Hemophilia

1. Hemophilia By: Abijah Minton Alfredo Sugawara Brandon Abad

2. Summary of Hemophilia • Hemophilia is a disorder where your blood doesn’t clot. • It is a recessive trait. • If a mom doesn’t have the gene for hemophilia and the father does, there son will not carry the trait for hemophilia but their daughter will. • Symptoms of hemophilia are excessive bleeding. Other people may experience life threatening hemorrhages with common injuries.

3. What Chromosome is your disorder located on? • This disorder is located on the x chromosome.

4. Mode of Inheritance • Someone would acquire hemophilia from sex linked traits. • If a trait is sex linked, then a gene is only carried by the male or female parent. Not by both.

5. Explaining Alleles • An allele is any of several forms of a gene, usually arising through mutation, that are responsible for hereditary variation. • Alleles come from a female and male parent. • RR stands for dominant alleles. rr is a recessive allele. Rr is the dominant gene over the recessive gene. • The dominant gene produces the same phenotype in the organism whether or not its allele identical. • The recessive gene produces its characteristic phenotype only when its allele is identical.
