Answer:

Your answer would be a autosomal dominant disorder.

____________________________________________________

Definition:

Autosomal Dominant Disorder:

A disorder in which could pass a disease from generations and on. In other words, future generations "inherit" the disease

____________________________________________________

Explanation:

The reason why "autosomal dominant disorder" is the correct answer because when a disease has been going on for many generations, this would be known as an autosomal dominant disorder, or ADD. What this means is that a person could have a mutant gene in them, also having a normal gene that is paired with  autosomal chromosomes. These diseases are inherited from a off spring that could take the disease and pass it on to their off springs, which would go on for generations due to the fact that it is a "dominant" trait. This is similar to the autosomal recessive disorder, but the autosomal recessive disorder needs two mutant genes in them, meaning that there is a less likely chance of getting the disease passed on to the off spring. The autosomal dominant disorder only needs one mutant gene in order to be effective during the inheritance for a offspring.

What is a telomere? What happens to telomeres each time DNA is replicated? How do cells prevent this from occurring?
vredina [299]
Telomeres are protective sequences of nucleotides found at the ends of chromosomes,Which become shorter every time a cell divides.
A gradual degeneration of an organism occurs, resulting in ageing.
However, some cells are able to replenish their telomeres using the enzyme telomerase. 
Hope this helps! :)
