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.
Answer: A . Large moving pieces of Earths lithosphere
Explanation:
The correct answer is B. The science of inherited traits
Explanation:
Genetics refers to the field in biology that focuses on studying genes which are the basic units of heredity and therefore the ones that determine inherited traits. Indeed genetic study the way traits are passed through reproduction and also the way genes change over time or express which is closely connected to evolution. Additionally, genetics have been widely studied beginning by the works of Mendel during the 19th century and nowadays the knowledge about genes including the behavior, function, and structure of them is broad. According to this, genetics is defined as the science of inherited traits.

Crossing over produces modern combinations of alleles. Not unused alleles but unused combinations which can result in modern phenotypes or expanded assortment of phenotypes. This way the there's expanded genotype/phenotype variety but the genuine qualities are still the same ones.
