Hemophilia is a hereditary bleeding disorder that primarily affects males. Why does this condition typically affect males more t

Ymorist [56]

Answer:

See the answer below

Explanation:

Hemophilia typically affects more males than females because the disorder is X-linked and recessive.

Females have two X chromosomes (XX) while males only have one X and one Y chromosome (XY). The two X chromosomes in females are capable of carrying alleles while the Y chromosome in males is hypothesized not able to carry alleles.

Consequently, the two X chromosomes in females will both need to carry the recessive allele of hemophilia in order for any female to be affected for hemophilia while the males only need their single X chromosome to carry the recessive allele in order to be affected.

In order words, the presence of a single recessive allele is not enough for a female to be affected while it is more than enough for a male to be affected. Hence, more males are affected b hemophilia disorder than females.

which classification level is broader than the kingdom level; which branch of biology is concerned with the naming and classifyi

shtirl [24]

Domain is broader than the kingdom level.

Levels of classification that are broader than phylum are regions and kingdoms. There are five kingdoms: Monrea, Protista, Fungi, Plants.

Taxanomy is the branch of biology concerned with the naming and classifying of organisms.

Protists are described as diverse organisms because they have many different characteristics. They are either heterotrophs or autotrophs. They are also eukaryotes that are not classified as plants, animals or fungi.

Animals group of organisms includes only multicellular heterotrophs.

If two species belong to the same class, they also belong to the same taxon higher up in the hierarchy. Here they belong to the same side and kingdom.

The gradual change in a species over time is called Evolution.

The levels of classification that are broader than the phylum are domains and kingdoms.

Taxonomy is the science of naming, describing and classifying all living organisms, including plants.
