Why is there a difference in the number of alleles for hemophilia and redgreen colorblindness between males and females?
The difference in the number of alleles for hemophilia and red-green colorblindness between males and females is due to the inheritance pattern of these genetic conditions. Hemophilia and red-green colorblindness are carried on the X chromosome. Males have one X chromosome and one Y chromosome, so they only need one copy of the gene to express the condition. Females have two X chromosomes, so they need two copies of the gene to express the condition.

In humans the alleles for hemophilia h is recessive. Which phenotype is displayed in an individual with the genotype XhY?
Genes that come together with different alleles are called _____.
Why is hemophilia more common in males than in females?
The genes associated with Hemophilia A and B are located on the X chromosome, which is one of the 2 sex chromosomes. For males, who have only 1 X chromosome, 1 altered copy of the gene in each cell is sufficient to cause hemophilia. In females, who have 2 X chromosomes, a mutation would have to occur in both copies of the gene to cause hemophilia. Since it is unlikely that females will have 2 altered copies of this gene it is therefor very rare for females to have hemophilia.
Can a genetic disease affect anybody?
Exceptions are always there e.g hemophilia and many bleeding disorders don't affect females.
Can a girl have hemophilia?
Yes females can have hemophilia. Although very rare it has been recorded. A female can get hemophilia if her mother is a carrier and her father has it. Like I said, It doesn't happen often but is possible.
