1. The data below show the phenotype of the offspring mean on the Y-axis plotted against the midparent on the X-axis. The line is the line of best fit through the data (linear regression). That line has a slope of 0.06, and the p-value of 0.13 (as p > 0.05, the relationship is not statistically significant). Does there appear to be a genetic basis for this character?

1- If additive genes contribute to all of the observed phenotypic variation for a quantitative characteristic, then what must be true? a-Narrow-sense heritability for this characteristic will be equal to 0.5 b-The mean phenotype of the parental generation will be equal to the phenotype of the individuals in F1 c-Broad-sense-heritability for this characteristic will be greater than narrow-sense heritability. 2- How can a geneticist find and map quantitative trait loci (QTLs)? a-By dividing the covariance by the product of the standard deviations of traits x and y b-By determining whether different genotypes for a known DNA marker also show variation in a quantitative characteristic c-By determining the selection response "R" and the selection differential "s" d-By calculating the genetic variance for a quantitative from the phenotypic and environmental variance asap please.
Which of the following interpretations for the missing hereditary are reasonable? 1. The reported high hereditary may have been over estimated by family studies 2. Genetic interaction and gene environment interactions are not easily captured 3. The variations with large effects are usually rare (frequency less than 0.5%) and that’s hard to be identified 4. All of the above

1. A sample of 600 individuals from a population is examined for the presence of the HindIII polymorphism in an autsomal Sca gene. There are two alleles of Sca gene, A and a. The results are 14 individuals are AA, 212 are Aa, 374 are aa. Please answer the following questions accordingly? How many alleles are present in the gene pool in the sample population fort he Sca gene? What are the genotype frequencies? What are the frequencies of A and a alleles? What are the expected numbers of the three genotypes, assuming random

3. Researchers are investigating a newly discovered condition that greatly increases the likelihood of lung damage associated with the use of e-cigarettes. They found that 2% of their study population has the condition. The researchers believe they have found a useful marker locus for assessing the presence of the condition in individuals with unknown family history. They have found that, of those individuals with the condition, 99% have the marker allele M1. Of those without the condition, 99.8% have an alternative allele M2 at the marker locus. What is the probability that an individual has the condition if they have marker allele M1 and what do you conclude about the utility of the marker locus for indirect diagnosis?

Mendelians emphasized continuous traits caused by heritable variation whereas Biometricians emphasized discrete traits caused by environmental variation. D. Mendelians emphasized discrete traits whereas Biometricians emphasized continuous traits. Both emphasized environmental variation.
John, noted acarologist (he studies mites) and fancy humming bird breeder hobbyist, is attempting to breed giant puffing humming bird that he can present at the fancy balls given in his glittering social circle. After years of experimenting with humming bird, John has found that the slope of the least squares regression of Midoffspring on Midparent values is 0.75. All the humming birds were allowed to breed, and a first batch of offspring was produced. The table below presents data on the puffing ability (in cm3) of 10 breeding families of humming bird in his dovecote: Family midparent mid offspring (first batch) 1 55 56 2 68 72 3 77 81 4 37 40 5 25 30 6 34 32 7 44 44 8 23 49 9 60 39 10 67 68 All the humming birds were allowed to breed, and a first batch of offspring was produced.
