In an effort to identify the influence of genetic factors on both Type 1 diabetes and Type Il diabetes, researchers calculated concordance rates for monozygotic twins. Concordance rates of 30-50% have been found for Type I diabetes with concordance rates of 80% for Type II. For both kinds of diabetes, dizygotic concordance rates were about 15%. What does this information suggest concerning the relative effect of genetic and environmental factors for each type of diabetes? O a. Type Il diabetes appears to be caused by a single, unidentified gene. O b. Genetic factors have little or no role in the occurrence of Type I diabetes. O c. Environmental factors have no role in the occurrence of either type of diabetes. O d. Type Il diabetes is primarily determined by non-genetic factors. e. Genetic influences exert a larger role in Type II diabetes than in Type 1 diabetes 1

Pairs of genetically related people were examined with regard to the rate at which they metabolize glucose. For 25 pairs of individuals that had each of the following relationships, correlation coefficients for glucose metabolism were determined: Mother-daughter: 0.36 Mother-granddaughter: 0.17e Sister-sister: 0.39 Sister-sister (fraternal twins): 0.40 Sister-sister (identical twins): 0.77 What is the average heritability for the rate of glucose metabolism in this group of females?
What is the frequency of the aa genotype if the frequencies of AA and aa are 0.19 and 0.36?
What are newest advances in early diagnosis and confirmation of Huntington disease? Explain the difference in inheritance pattern and the frequency to have affected progeny in the case of these three inherited diseases: Huntington, Cystic fibrosis and Duchenne muscular dystrophy. What therapies can be used or recommended for patients experiencing any of these inherited diseases?
I'm having trouble finding the dependent and independent variables of this scenaro: Average IQ scores for young school children are known to be 100 (SD = 15). However, the literature indicates that children’s intelligence may be decreased if their mothers have German measles during pregnancy. Using hospital records, a researcher obtained a sample of n = 25 school children whose mothers all had German measles during their pregnancies. Do the data indicate that children born to mothers who had German measles during the pregnancy have significantly lower IQ scores than typical young school children?
point pu What is the most appropriate description of the role of heritability in bbesity? O The huge impact of rare mutations in specific genes on obesity illustrates the important role of heritability in the current obesity epidemic. O The role of heritable factors is equally important for obesity as it is for height. O The role of heritable factors in obesity has remained relatively dormant for centuries until the emergence of the obesogenic environment brought them to life. O The role of heritability in obesity is very limited as our genes haven't changed over the past 50 years yet the population has become a lot more obese.
In investigating whether stress is a factor in aging, telomere length was measured in women with chronically ill children, and compared to the number of years since the child's diagnosis. Use the following summary data to calculate the correlation coefficient between telomere length and chronocity: Summary data: Sum of products: -11.564 Sum of squares for chronicity: 311.422 Sum of squares for telomere length: 2.499 Total sample size: 39
Six single-nucleotide polymorphism (SNP) loci are known to contribute to the development of type 2 diabetes. Diabetes is certain if eight or more of the alleles at these six loci are of the “contributing” variety. An uppercase letter indicates an allele that contributes to diabetes and a lowercase symbol indicates a noncontributing allele. A married couple wants to know the probability of producing a child who is at severe risk of type 2 diabetes. Their genotypes were determined by microarray analysis and are as follows: AaBbccDDEEFf × AaBbCCDdEeFf
Which of the following experimental observations suggest that adisease has a genetic basis?A. The frequency of the disease is less likely in relatives that liveapart compared with relatives that live together.B. The frequency of the disease is unusually high in a small groupof genetically related individuals who live in southern Spain.C. The disease symptoms usually begin around the age of 40.D. It is more likely that both monozygotic twins will be affectedby the disease than will dizygotic twins.

What is the relationship between beta-amyloid and the protein APP? How does the APP protein differ in a person with the Alzheimer's-risk version of this gene compared to the neurotypical populations?
The major phenotype of deficiency of protolithic enzyme alpha-antitrypsin is the destruction of pulmonary alveoli resulting in chronic obstructive pulmonary disease or emphysema. The gene for this enzyme is highly polymorphic, with more than 70 different alleles described. 90% of white Europeans have MM genotype (normal). Two mutant alleles, S and Z, account for most of the disease associated with alpha-antitrypsin deficiency. The flowing table tabulates frequencies of different clinically important genotypes in the French population. Genotype Frequency MM 0.90 MZ 0.04 SS 0.001 SZ 0.0012 ZZ 0.0004 Using the data presented, calculate the allele frequencies for Z and S.
