Hemophilia is caused by a defect in the genes responsible for the formation of blood clotting factors viii and ix. These genes are located on the X chromosome. A female has two X chromosomes and a male has an X chromosome and a Y chromosome. Therefore, all the daughters of a hemophiliac father will be the carriers of this disease, and half of his sons acquiring the X chromosome from the father will have the disease.

Answer:
Another Asp in something like a deep pocket; a superficial amino acid binding pocket with either a slight neutral side, neither elastase nor trypsin.
Explanation:
- Almost all trypsin as well as elastase contain catalytic triads. In trypsin, aspartate is the essential amino acid throughout the bag. The latter's pocket also becomes unique to charged particles (+) side-chain creatures.
- Elastase seems to have a pocket which really combines multiple valine residues, making it extremely difficult to reach the pocket with large bulky main chain, this therefore prefers short side chains.
The homologs with chymotrypsin include trypsin but mostly elastase. As either a central amino acid, chymotrypsin encompasses serine.
The question refers to the following table, which compares the percent sequence homology of four different parts (two introns and two exons) of a gene that is found in five different eukaryotic species. Each part is numbered to indicate its distance from the promoter (for example, Intron I is the one closest to the promoter). The data reported for species A were obtained by comparing DNA from one member of species A to another member of species A.
Regarding these sequence homology data, The principle of maximum parsimony would be applicable in Inferring evolutionary relatedness from the number of sequence differences.
What is principle of maximum parsimony?
Maximum A phylogenetic tree can be inferred using the character-based method of parsimony by reducing the total number of evolutionary steps needed to explain a given set of data assigned to the leaves.
Generally speaking, the parsimony principle states that it is preferable to use the simplest explanation possible to explain the data. Parsimony in phylogenetic analysis refers to the notion that a relationship hypothesis that calls for the fewest character changes is more likely to be accurate.
Therefore,
The principle of maximum parsimony would be applicable in Inferring evolutionary relatedness from the number of sequence differences.
