Answer:
1.1 that's 1 in 7 and it's most common in adolescents
Answer:
The disease is autosomal dominant.
Explanation:
Huntigton's disease is an autosomal dominant disease because the allele for this disease is present on an autosomal chromosome and the person with even one mutated allele (H) can develop the disease even if he has one normal allele (h) too. If a person is affected with Huntigton's disease, there are 50 percent chances that the children will also suffer from the disease.
For example: A father is suffering from Huntigton's disease but mother is normal. Let us see how it will be passed to kids.
P1: Hh : hh
Gametes: H : h: h: h
Offspring: Hh: Hh: hh: hh
50% : 50%
Therefore, 50 percent chances are there that the kids will have disease even if only parent suffers from it.
Answer:
The correct answer is D the frequency of O allele is 0.66
Explanation:
The correct answer is D because
A the heterozygote frequency is 0.55.
C the UU genotype frequency is 0.44.
D O allele frequency is 0.66.
E All genotype frequency sums up to 1.
