Please help with the following: How does penetrance differ from expressivity in genetics? A. Penetrance is the percentage of individuals with a specific genotype that exhibit the expected phenotype while expressivity is the degree to which a phenotypic character is expressed. B. Penetrance is the degree of lethality of a specific genotype while expressivity is how frequently that genotype is seen in the population. C. Penetrance is the presence of more than two alleles at a locus within a group of individuals while expressivity is the influence of sex on which alleles express themselves. D. None of the above. E. Penetrance refers to the paternal effects of a gene while expressivity refers to the maternal effects of a gene.

How might the Hardy Weinberg relationship be used to evaluate a new SNP genotyping technology using multiple individuals from a population? Group of answer choices a)If genotypes match the reference genome, the technology is sound. Otherwise, the technology may have problems accurately calling SNPs. b)If observed phenotypes follow Hardy Weinberg, the technology is sound. Otherwise, the technology may have problems accurately calling SNPs. c)If genotypes and allele frequencies follow Hardy Weinberg, the technology is sound. Otherwise, the technology may have problems accurately calling SNPs. d)None of the above

Identification of regions of the genome that are associated with a trait. d. Identify haplotypes associated with specific traits of interest in other populations.
Please help with the following: Lactase persistence is an adaptation to milk drinking that has developed since the beginning of agriculture ~10 KYA. What is the relationship between the alleles driving this ability in European, Indian and African populations? A. One allele is responsible for lactase persistence in Europeans and Indians because of where agriculture originated and was introduced through migration. routes. B. The allele responsible for lactase persistence in all three populations is the same allele on the LCT gene. C. Different alleles are responsible for lactase persistence in each population. D. One allele is responsible for lactase persistence in Europeans, but other alleles cause the trait in Indian and African populations. E. One allele is responsible for lactase persistence in Africans, but other alleles cause the trait in European and Indian populations.

Select all that apply. Group of answer choices a. Compare Korean individuals with the disease to unaffected Korean individuals b. Pursue SNPs only in exonic loci for further study c. Pursue SNPS only in genes related to kidney development for further study d. Set strong statistical thresholds to identify SNPs related to the disease state over the general variation observed in populations e. Compare Korean individuals with the disease to every available genome for a stronger statistical power.
Identify a possible advantage and a possible disadvantage of a genetic test that would identify genes in individuals that increase their probability of having Alzheimer’s disease later in life.
Which of the following statements about Mendelian or complex disease is TRUE? Question options: Genetic methods for studying Mendelian phenotypes, such as crossing, is not useful for mapping quantitative trait loci. Mapping of quantitative trait loci does relies on genetic variations that directly contribute to the trait of interest. Both Mendelian and complex traits are associated with single gene locus. Genetic factors determine Mendelian traits, while environmental factors determine complex traits. Genome-wide association studies rely on polymorphic markers that are in linkage disequilibrium with alleles that contribute to the trait of interest.
For each of the following characteristics, indicate whether it would be considered a discontinuous characteristic or a quantitative characteristic. Briefly justify your answer. a. Kernel color in a strain of wheat, in which two codominant alleles segregating at a single locus determine the color. Thus, there are three phenotypes present in this strain: white, light red, and medium red. b. Body weight in a family of Labrador retrievers. An autosomal recessive allele that causes dwarfism is present in this family. Two phenotypes are recognized: dwarf (less than 13 kg) and normal (greater than 23 kg). c. Presence or absence of leprosy. Susceptibility to leprosy is determined by multiple genes and numerous environmental factors. d. Number of toes in guinea pigs, which is influenced by genes at many loci. e. Number of fingers in humans. Extra (more than five) fingers are caused by the presence of an autosomal dominant allele.
Consider the case of a hypothetical genetic disease called WhySciEleven (WSE), an inherited disease that results to the inability to complete production of an amino acid “moduleactivity” that results in brain damage if untreated. WSE is due to a recessive allele. Given one WSE occurrence per 10,000 births. Which term in the Hardy-Weinberg equation corresponds to the frequency of individuals who have no alleles for the disease WSE? a. p b. 2pq c. p2 d. q2
In Huntington’s disease, the wild-type allele, h, is recessive to the disease allele, H. The persistence of an autosomal dominant allele that is fatal in 100% of cases is best explained by which of the following? A) The dominant allele only has moderate negative effects during adolescence and young adulthood. B) The wild-type h allele continues to spontaneously mutate into the dominant H allele. C) The persistence of any given allele in nature is determined almost wholly by chance. D) The disease has no effects until the individual has reached an age far past the normal age for reproduction.
