The best way to illustrate the relative frequency distribution is a percentage or a proportion.
For example, imagine that in the survey conducted above 80 people where interviewed and 35 were democrat, 24 republican, 12 libertarian, and 9 chose another party.
- Absolut frequencies would be the number of responses for each option: 35, 24, 12 and 9.
- Relative frequency (democrats) = 35/80 = 0.4375= 43,75 % of the participants
- Relative frequency (republicans)= 24/80= 0.3 = 30% of the participants
- Relative frequency (libertarians)= 12/80= 0.15 = 15% of the participants
- Relative frequency (others)= 9/80= 0.1125 = 11,25 % of the participants
Answer:
The most likely cause of this disease is that siblings have a variable expression of this disease.
Explanation:
Neurofibromatosis 1 is an autosomal dominant disorder, even though it is a very rare disease to occur. This dominant nature causes this disease to be expressed even in people who have heterozygous alleles for it, which makes it easier for siblings to have this disorder, since only those who are hom0zygous recessive would not present it. However, the expressiveness of the disease may vary between siblings, as is the case shown above, where although the two siblings have the same disease, they present it in different ways.
