What was the value for h²?a.For what specific trait, therefore, do they demonstrate heritability?b. Can that trait evolve?C.What if they studied the same trait in a different population and got a value of h²=0.4.Which population would evolve faster?7. Explain the authors' reasoning for rejecting body condition affecting parasite load (see 3rdparagraph of Discussion). Draw a hypothetical graph that corresponds to their description ofwhy they rejected the hypothesis.8. Describe the problem of uncertain paternity with respect to this study.

1. The electrophoresis gel below shows allozyme polymorphisms of the sevenless gene (Sev) from 16 individuals sampled from a Drosophila melanogaster population. Assume that all genotypes of Sev in the population were sampled. a. Please estimate the genotype frequencies and allele frequencies of this population. b. Please compute the heterozygosity (h) of this gene. %3D
1). The p-value for this test is . 072. Do we reject the null hypothesis?2). Is there sufficient evidence to conclude that there is a statistically significant difference in mean weight between the different NYHA groups?3). Pretend for a moment that the resulting p-value was 0.02. Do we reject the null hypothesis in this case? Why or why not? If we were to reject the null hypothesis, we would conclude that there is sufficient evidence to suggest a statistically significant difference in mean weight between the NYHA groups. The NYHA variable has four levels: would we know which of the four NYHA group means gave the statistically significant result?

Through PCR, we have determined the PER3 genotypes for a class of students as follows: H4/H4 = 125 individuals; H4/H5 = 90 individuals and H5/H5=85 individuals. Considering the Hardy Weinberg equilibrium and calculating the Chi-square statistic, do you reject or fail to reject the null-hypothesis? 1. Comparing the value of Chi-square that I calculated with the critical value of Chi-square for the appropriate degrees of freedom I conclude that P<0.05. Hence, I reject the null hypothesis. 2. Comparing the value of Chi-square that I calculated with the critical value of Chi-square for the appropriate degrees of freedom I conclude that P>0.05. Hence, I reject the null hypothesis. 3. Comparing the value of Chi-square that I calculated with the critical value of Chi-square for the appropriate degrees of freedom I conclude that P<0.05. Hence, I fail to reject the null hypothesis. 4. Comparing the value of Chi-square that I calculated with the critical value of Chi-square for the…

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.

Mendelians emphasized discrete traits whereas Biometricians emphasized continuous traits. Both emphasized heritable variation. C. Mendelians emphasized continuous traits caused by heritable variation whereas Biometricians emphasized discrete traits caused by environmental variation. D.

Please 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. Linkage disequilibrium measurements may be utilised to infer the history for alleles. ii. Proportions for alleles in linkage disequilbrium may be used in models involving selection, genetic drift, or migration to estimate when an allele originated in a population. iii. The allele CCR5-Δ32 is common among European populations possibly because selection operated positively on individuals containing the allele when the bubonic plague pandemic swept through northern Europe in the 14TH century.iv. The allele CCR5-Δ32 is common among European populations possibly because genetic drift effects allowed frequencies to fluctuate stochastically over several thousand years to its current level. v. The allele CCR5-Δ32 possibly originated several thousand years ago. Question 2 options:…
