Many mutagens will not reach the gonads - but those that enter your bloodstream eg the toxins in cigarette smoke can reach them. Turner syndrome is a condition of females who, in the classic form, carry only a single X chromosome 45,X. Each "human body cell" has 46 chromosomes. What do you think of this line Inquiry occurs completely with excessive familiarity with the physical looks of an object?
In brief, at some point in early development one X chromosome in each somatic cell of a female embryo undergoes chemical modification and is inactivated so that gene expression no longer occurs from that template.
The phenomenon of X inactivation prevents a female who carries two copies of the X chromosome in every cell from expressing twice the amount of gene products encoded exclusively on the X chromosome, in comparison with males, who carry a single X. Get your answers by asking now.
These safety measures mean that even the most common genetic disorders are comparatively rare, but their occurrence in the general population means that the DNA checks and redundancy are not foolproof. What are the factors that impact recruitment in organizations?
