The endocrine system is characterized by the secretion of hormones by target cells.
<h3>What about the endocrine system is true?</h3>
Endocrine glands produce hormones into the bloodstream. As a result of this, the hormones can now reach cells throughout the body. The regulation of mood, development, metabolism, and reproduction is aided by the endocrine hormones. The endocrine system regulates how much of each hormone is released.
<h3>What are the traits of the endocrine system?</h3>
Endocrine glands are ductless, their secretions are directly emptied into the circulation while exocrine glands have ducts. Endocrine glands are distinguished by their ductlessness, high degree of vascularization, and presence of intracellular vacuoles or granules that store hormones.

Answer:
The alleles I a and I b are the alleles that works for identifying unique antigen.
Explanation:
These alleles are generally found as deposition on the surface of the red blood cells. Again, these antigens are different form made from one protein. The Ia and I b alleles are found to be co-dominant and allele i is recessive. In human beings three different alleles are there, Ia, I b and I. The alleles are nothing, but a form of gene. Many genes are there having different function but are present in the same position. Humans are diploid, hence have two allele, each from one parent it has been inherited.

CHROMATIN : It can be simply referred to as genetic material in loose or normal form. It can be DNA or RNA inside the plant or animal cell's nucleus.
2. CHROMOSOME : When the chromatin material is condensed prior to the cell division and get highly organized form that can be visible in form of proper structures have two chromatids, they are called chromosomes.
The process of formation of chromosomes from chromatin occurs mainly in prophase of Mitosis or Prophase II or Prophase I of Meiosis.
3. CHROMATID : Chromatid is also referred to as sister chhromatids since there are two chromatids present in one chromosome that are almost similar. Chromatids can be considered as arms of chromosomes which are attached at a point centromere (please see the image for better understanding).
