Kruka [31]

Researchers selected candidate genes by identifying homozygous tracts shared by all three siblings along with the parental phenotype, this type of study is applied for the inheritance of recessive genes. Since the recessive genes can not be expressed in heterozygous genotype, the back tracking of carriers and homozygous recessive individual will help understand its inheritance pattern. The inheritance of dyt2 can be autosomal recessive. It is usually passed on to progeny of two carriers.

What types of antigen do T cells NOT recognize? What types of antigen do T cells NOT recognize? self-antigens bacterial antigens
Stolb23 [73]

Answer:

Self-antigens are not recognized and attacked by the T cells.

Explanation:

In immunology, the antigens are those substances which are bound by the antibodies. The antigens can be originated from within the bodies, known as self antigens or from outside the body, known as non-self antigens. The immune system identifies and attacks non-self invaders or the foreign harmful objects present in the body. It does not attack the self-antigens under the normal conditions. This is due to the negative selection of T cells of the thymus.
