- What kind of test would best determine whether genotypic frequencies match the Hardy-Weinberg model? Group of answer choices Chi-square with three rows (homozygous dominant, heterozygous, homozygous recessive) Chi-square with two rows (dominant and recessive alleles) T-test between homozygous and heterozygous T-test between dominant and recessive allelesarrow_forwardPlease use the following table to compare qualitative (Mendelian) traits and quantitative traits (complex traits) - choose from the following.arrow_forwardThe following table gives the percentage of twin pairs studied in which bothtwins expressed the same phenotype for a trait (concordance). Percentages listedare for concordance for each trait in monozygotic (MZ) and dizygotic (DZ) twins.Assuming that both twins in each pair were raised together in the sameenvironment, what do you conclude about the relative importance of genetic (H)versus environmental (E) factors for each trait?Traits MZ, % DZ, % H EBlood types 100 66Eye color 99 28Measles 95 87Diabetes 65 18Mental retardation 97 37arrow_forward
- What is a normal distribution? Discuss this curve with regard toquantitative traits within a population. What is the relationshipbetween the standard deviation and the normal distribution?arrow_forwardPlease assess the lowercase-Roman-numeral-labelled statements that appear immediately below and click the uppercase-letter-labelled response that is presented below and conveys the most accurate information. i. Phenotypes for quantitative traits are determined by multiple alleles at multiple loci. ii. Phenotypes for quantitative traits can be influenced during development by environmental factors. iii. Height exemplifies a quantitative trait in humans.iv. What appears to be a classic Mendelian trait could in fact be a quantitative trait but with one locus contributing a very, very, very large effect and many other loci contributing very, very, very small effects. v. Quantitative trait loci must occur on the same chromosome. Question 3 options: A) Statements i and ii convey inaccurate information. B) Statement v conveys inaccurate information. C) Statements i, ii, and iii convey inaccurate…arrow_forwardThe F2 distribution of three human traits are shown in the graphs below.
