Unequal crossing over during Prophase I can result in one sister chromosome with a deletion and another with a duplication. A mutated form of hemoglobin, known as hemoglobin Lepore, is known in the human population. Hemoglobin Lepore has a deleted set of amino acids. If it was caused by unequal crossing over, what would be an expected consequence?

A) There should also be persons whose hemoglobin contains two copies of the series of amino acids that is deleted in hemoglobin Lepore.

B) Each of the genes in the hemoglobin gene family must show the same deletion.

C) The deleted gene must have undergone exon shuffling.

D) The deleted region must be located in a different area of the individual's genome.

Answer:

A) There should also be persons whose hemoglobin contains two copies of the series of amino acids that is deleted in hemoglobin Lepore.

Explanation:

The process of crossing over generates recombinant chromatids that carry the exchanged genetic segments. In case of unequal crossing over, a part of the genetic segment is missing from one recombinant chromatid of a homologous chromosome and is inserted into the recombinant chromatid of the corresponding homologous chromosome. The gamete that obtains the chromosome with an additional genetic segment would give rise to a person carrying the duplicated amino acids that are otherwise missing from the chromosome of the person expressing hemoglobin Lepore.

What adverse response is known to occur in people who drink copious amounts of water while participating in intense physical act
MArishka [77]
The correct answer is hyponatremia. This is also called water intoxication in athletes. Water is a substance that is devoid of any solutes and electrolytes. The major extracellular electrolyte sodium is present in the extracellular fluid and the plasma. In the event of increased water intake, the sodium in the plasma will be diluted hence will cause hyponatremia.

The scala media is rich in K+ while the scale vestibuli and tympani are rich in Na+.
o-na [289]

Answer:

The given statement is True.

Explanation:

Scala media has endolymph as its constituent and endolymph  is rich in Potassium ions (K+)

whereas

Scala tympani and  scala vestibuli has in its composition Perilymph and Perilymph has sodium ions as their major constituent ions.

Therefore, scala media is Potassium ion rich while scala tympani and vestibuli are sodium ion rich.
