What genes direct the
Valentin [98]

Answer:

a. hox genes.

Explanation:

HOX genes have the following functions:

  • HOX genes are the homeobox subset.
  • They specify the areas of the embryo's body plan along the animal head-tail axis.
  • They are encoding Hox proteins that specify the position characteristics and ensure that the right structures form at the right position in the body.
  • They regulate high-level executive genes, such as transcription factors and intracellular signaling molecules, which adhere, number, form, and growth to cells.

The vertebrates are highly preserved.

The clusters and other genes occur uninterrupted.

Evolutionary, the heterogeneous regulatory areas between the genes most previously present are larger and more preserved than those present at the other ends of the clusters.

The characteristical feature is that these are homeodomain proteins with a highly preserved area of DNA binding encoded with homeobox gens.

Its a sex linked disorder and it makes stopping the bleeding slower in affected individuals.

<h3><u>Explanation:</u></h3>

Hemophilia is a sex linked recessive disorder which occurs due to a gene present in the X chromosome. The presence of this gene in males surely make the individual hemophilic because the Y chromosome doesn't contain any dominant factor of this gene. In females, the recessive individuals become carriers without expression of this gene. Only the dominant individuals in females expresses Hemophilia.

Its a disease where the Christmas factor (Factor IX) or the antihemophilic factor(Factor VIII) is absent in the affected individual. This makes the cascade theory incomplete and there's a defect in blood clotting in both the intrinsic and extrinsic pathways. Thus the persons if starts bleeding, loses a lot of blood before coming to a stability.
