I need help with the following question
Step by step
Solved in 2 steps
- A researcher examines a locus, or marker, in which there is a particular C/T polymorphism in a population of interest. Let’s call this Locus 1. They obtain the following genotype counts in a sample of the population: CC:42, CT:16, TT:32. a) Calculate the genotype frequencies and the allele frequencies for Locus 1 in the sample.b) Calculate the observed heterozygosity (the frequency of heterozygotes) and the observed homozygosity (the total frequency of all homozygotes) in the sample. Ensure that these two frequencies add up to 1.Here C has 2 alleles C1 and C2 and same with D allele. C1D1 are the haplotypes for both of the populations: C1 D1 C1D1 First Population 0.3 0.5 0.45 Second Population 0.5 0.2 0.15 Answer the following: 1. If you sample 2 copies of the gene that is C from first population what can be the probability that they are both C1 alleles? 2. You have sampling an C1 allele from 1st popu. If you sample one more copy from first population, what is the probability that it will also turn out to be allele that's C1? 3. Find the expected frequency of haplotype from 1 st population.Imagine a population of raccoons in which food-washing behaviour is controlled by the W locus. WW individuals wash their food thoroughly before eating; Ww individuals wash their food less thoroughly; and ww individuals never wash their food. After observing 1000 raccoons, you count 300 WW, 200 Ww and 500 ww individuals. What is the frequency of the w allele for this population? A. 0.5 B. 0.6 C. 0.7 D. Because the population is not in Hardy-Weinberg equilibrium at this locus, it is impossible to calculate the frequency of allele w.
- 60 individuals have the genotype AA28 individuals have the genotype Aa12 individuals have the genotype aaWhat is the frequency of the A allele?Think of how many alleles in total?hint: add up the number of A alleles in this population: AA= 60+60 and Aa= 28.Add those together and divide by the total number of alleles.A gene has two alleles that are associated with body mass in an additive manner. The table below shows the mean phenotype for each genotype, along with the frequency of each genotype in a population. Use this information to answer the following questions. A1A1 A1A2 A2A2 Mean mass (kg) 50 55 60 Frequency 0.01 0.18 0.81 a) How much does this locus contribute to additive genetic variation? b)A second locus (B) has two alleles (B1 and B2), which are also associated with body mass in an additive manner. Each copy of the B2 allele adds 2 kg of mass. The B2 allele is at a frequency of 0.6 in the same population as the A alleles are found. How much does the B locus contribute to additive genetic variation? c) Assume that these two loci are the only sources of additive genetic variance for body mass. The total phenotypic variance for body mass in the population is 10 kg2. What is the narrow sense heritability (h2) of body mass in this population? d)…A gene has two alleles that are associated with body mass in an additive manner. The table below shows the mean phenotype for each genotype, along with the frequency of each genotype in a population. Use this information to answer the following questions. A1A1 A1A2 A2A2 Mean mass (kg) 50 55 60 Frequency 0.01 0.18 0.81 a) How much does this locus contribute to additive genetic variation? b)A second locus (B) has two alleles (B1 and B2), which are also associated with body mass in an additive manner. Each copy of the B2 allele adds 2 kg of mass. The B2 allele is at a frequency of 0.6 in the same population as the A alleles are found. How much does the B locus contribute to additive genetic variation?
- While studying the frequency of sickle-cell disease ("sickle cell anemia") in a population living in sub-Saharan Africa, you obtain the following data from a sample of n= 100 people (note that I chose a simpler system for identifying the alleles rather than using "Hb S" for sickle cell allele), which is the actual name and what you used in lab). What is the frequency of the sickle cell allele (b) in the sample below from a human population? Sample Data BB-60 individuals (No sickle cell disease) Bb-30 individuals (No sickle cell disease) bb-10 individuals (Sickle cell disease) 1. 0.25 2. 0.10 3. 0.35 4. 0.60 5. 0.20Imagine the unlikely case that the 11 individuals represented in the gel image above were truly representative of the population. If 1 is the largest and 7 the smallest allele; what is the frequency (f) of allele 5? Give your answer as a percentage, to one decimal place, do not include the % symbol. ANSWER: The frequency (f) of allele 7 in the gel image below is ?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 matings.
- The table below shows four human populations (CLM, MXL, PEL, PUR). A single nucleotide polymorphism with alleles A and G has been genotyped in each of these populations. For each genotype, the frequency is shown, and the number of individuals with that genotype in the sample is in brackets. What is the frequency of the A allele in the CLM population? 0.80 0.76 0.88 0.84In a population of snails, a locus affecting shell color has 2 alleles. The D allele produces a dark shell, while the d allele produces a white shell. Heterozygote individuals (Dd) have a yellowish shell. In a sample of 150 snails, 47 snails have a white shell, and 12 have a yellow shell. What is the frequency of the D allele? Round your answer to the second decimal place (0.00)Cystic fibrosis is a genetic disease mostly affecting people of European descent that is caused by a recessive allele. You sample 1000 people for this allele and find 772 homozygous normal individuals, 221 heterozygotes, and 7 people homozygous for cystic fibrosis. Is this population in Hardy-Weinberg equilibrium?
