How many pair of chromosomes are there in a hemophiliac individual?
Question: How many pair of chromosomes are there in a hemophiliac individual?
Hemophilia is a genetic disorder that is typically inherited in an X-linked recessive pattern. This means that the gene mutation responsible for hemophilia is located on the X chromosome, which is one of the two sex chromosomes. Males have one X and one Y chromosome, while females have two X chromosomes.
Since hemophilia is an X-linked recessive disorder, males who inherit the gene mutation on their X chromosome will have hemophilia, while females who inherit one mutated X chromosome may be carriers of the disorder but are often asymptomatic.
Therefore, a hemophiliac individual with the typical form of the disorder will have one X chromosome with the mutated gene and one Y chromosome, giving them 22 pairs of autosomes (non-sex chromosomes) and one pair of sex chromosomes (X and Y). In rare cases, females can also have hemophilia if they inherit the mutated gene on both X chromosomes.
