B cells are at the centre of the adaptive humoral immune system and are responsible for mediating the production of antigen-specific immunoglobulin (Ig) directed against invasive pathogens (typically known as antibodies).

T cells are a part of the immune system that focuses on specific foreign particles. Rather than generically attack any antigens, T cells circulate until they encounter their specific antigen. As such, T cells play a critical part in immunity to foreign substances.

Which of the following is NOT TRUE about Y-linked disorders?
Usimov [2.4K]

Answer:

<em>The statement which is not true is C) They can affect males or females</em>

Explanation:

All the chromosomes in a person are known to be autosomal chromosomes except for the sex chromosomes. The sex chromosomes are of two types: Chromosome X and chromosome Y.

Both the sex chromosomes are X in females. Males have one X chromosome and one Y chromosome. The Y chromosome is shorter than the X chromosome. The Y chromosomes occur only in males. Hence, Y- linked disorders will affect only males. These disorders will never occur in females.
