What is the typical F2 ratio in the case of dominant epistasis?
inysia [295]

Answer:

12:3:1

Explanation:

<em>The typical F2 ratio in cases of dominant epistasis is 12:3:1.</em>

<u>The epistasis is a form of gene interaction in which an allele in one locus interacts with and modifies the effects of alleles in another locus</u>. There are different types of epistasis depending on the type of alleles that are interacting. These include:

  • Dominant/simple epistasis: Here, a dominant allele on one locus suppresses the expression of both alleles on another locus irrespective of whether they are dominant or recessive. Instead of the Mendelian dihybrid F2 ratio of 9:3:3:1, what is obtained is 12:3:1. Examples of this type of gene interaction are found in seed coat color in barley, skin color in mice, etc.
  • Other types of epistasis include <em>recessive epistasis (9:3:4), dominant inhibitory epistasis (13:3), duplicate recessive epistasis (9:7), duplicate dominant epistasis (15:1), and polymeric gene interaction (9:6:1).</em>

mote1985 [20]

Answer:

Answered below

Explanation:

Head injuries may be penetrating head injury or closed head injury.

A major concern for health professionals regarding intracranial injuries resulting from closed head traumas, is the management of intracranial pressure. Elevated intracranial pressure have negative effects on the brain and immediate management of raised intracranial pressure is important to avoid cerebral edema, intracranial hematoma, brain herniation and even death.

The usual procedures in the management of head injury include elevating the head to about 30 degrees. This position promotes cerebral venous drainage and decreases intracranial venous pressure and intracranial pressure as well.

This is helpful because when the patient is left in the horizontal position, the intracranial pressure becomes significantly higher and the have fatal consequences.
