Explanation:
Hemophilia is a disease that is characterized by an abnormal blood clotting process. There are many different proteins that are involved in the clotting process and a single mutation or change in one of them could result in serious effects. Hemophilia is characterized by an abnormal version of one of the many proteins involved in the clotting process, the proteins that are commonly affected are the coagulation factor 8 or 9 (VIII or IX). These abnormal proteins are caused by a mutation in the gene (within the DNA) that codifies for the production of each protein. In other words, a mutation in the part of the DNA, (gene F8) will lead to a dysfunctional coagulation factor VIII and a mutation in the gene F9 will lead to a dysfunctional coagulation factor IX. Importantly, these mutations could be inherited and could cause hemophilia. Therefore, an error in the DNA and subsequently, an error in the protein will cause hemophilia. Finally, it is important to mention that there are other types of hemophilia that are not caused by the above-mentioned mutations, such as acquired hemophilia.
1st one i think, hope that helped
Answer:
4 allopatric
Explanation:
The formation of a new species can occur in several ways. One such process is the separation of two populations of a species geographically. The presence of any geographical barrier may separate the two populations from each other. These populations accumulate variations over time. After several generations, the members of these two populations can not interbreed successfully and are said to be reproductively isolated. The two populations are now two different species. This is called allopatric speciation.
