The hemophilia gene works similarly to the diagram shown up above. Women can have hemophilia, but they can also be carriers, which means they have both the hemophilia gene and a non-hemophilia gene, which is dominant, so it blocks the hemophilia gene out. Since men do not have two X chromosomes, they either have hemophilia or they don't, and they can't be carriers. A woman needs two recessive hemophilia genes to actually have hemophilia.
Hemophilia is a disease i've known about. No one in my family has it, but i've read about it being in others. An interesting fact about Hemophilia is that for a time hemophilia affected many members of European royalty thanks to Queen Victoria of Britain being a carrier of the disease and having a lot of kids who married into other European royal families. Fortunately, medical care for hemophilia is more advanced than it was back then.
Good information and was interesting to read
ReplyDeleteI like the information you put in and the way you formatted it. Very organized, I understood everything that I read. Also the picture you chose was very helpful and went well with the topic.
ReplyDeleteYour information was very accurate and well organized. The reflection was very well stated. The only thing you left out is there is hemophilia A, and hemophilia B
