Solved in 2 steps
- A-CREB is a CREB allele that is dominantly negative. Why would you employ A-CREB in a research study?In a horse population, three diferrent traits showing continuous distribution were measures, and their variances are shown in the table below: Calculate the broad sense and narrow sense heretabilities for each trait.Connection to Quantitative traits: SNPs are inherited in a Mendelian fashion and are often polygenic in nature. We can think of SNPs in terms of either contributing or non-contributing alleles. A study of SNPs correlated with heart disease has shown that heart problems are severe if 9 or more of the alleles at 6 loci are of the contributing variety. What is the probability the following parents will have a child that is susceptible heart disease? AaBbccDDEEFf x AaBbCCDdEeff
- Calculate the Variance of the following data set: 10, 15, 13, 12, 14Given an observed F2 data set, a specified gene, and two phenotype classes (disease and wild type), the number of degrees of freedom for the chi-square goodness of fit test when studying the F2 generation is: A)-1. B)0. C)2. D)1. E)3.A a soybean breeder is aiming to breed for early maturation. He was able to cross variety A which has desirable agronomic characteristics but late maturation with variety B which has less-than-ideal agronomic characteristics but early maturation. In addition to the F1 population, F2 and BC1 population were also generated. The variances for each population are presented below.
- Describe in your own words what variance measures. Then explain why the variance of both samples must be used in the calculation of a t-test (In other words, explain why we have to factor in the variance when comparing the means).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.An investigation of shrew tail length showed that the length of tails varied from 24mm to 66mm. In one generation recorded out of a population of 2,360 shrews only 2 were as long as 66mm. In another cross a new true-breeding shrew variety was used which gave a range of F1 tail lengths with a variance of 0.316. In the crosses using the original variety there was an even greater range of tail lengths and a variance of 0.725. What can you conclude about the heritability (H2) of tail length in the original shrews?
- In a horse population, three different traits showing continuous distribution were measures, and their variances are shown in the table below: Calculate the broad sense and narrow sense heritabilities for each trait.The mean, standard deviation, variances, and coefficient of variance of plant height from two rice plants (P1 and P2) and their progeny (F1 and F2) and a backcross generation (P1 x F1) are shown below. Calculate the broad-sense heritability of plant height in this species and interpret the results.Which of these is not true of single nucleotide polymorphisms (SNPs)? are single base-pair variations in the genomes of the human population are genetic markers used to study the genetic basis for disease vary from 1-3 bases in length are the most common type of genetic variance
