B. Based on fitness value we can state that directional selection has been enacted which is favoring MM genotype as the fitness value of MM individuals is the largest I.e., 1.
9. In another population the frequency of individuals with each genotype is MM = 0.25, MN=0.45,...
0.9 points Consider a population of 100 individuals and the frequency of the Aalele is 0.6 and the frequency of the alle is 04. If the following fitness values for each genotype are applied to the next generation what be the frequency of the A allele in the next generation? WAA1 WA0.25 was 0.25 a o oo
Consider a population of 100 individuals and the frequency of the A allele is 0.6 and the frequency of the a allele is 0.4. If the following fitness values for each genotype are applied to the next generation, what will be the frequency of the A allele in the next generation? wAA = 1 wAa = 0.25 waa = 0.25 Answer Choices: a. .81 b. .64 c. .92 d. .73 e. .54
A sample of 2,000 individuals from a human population was scored for MN blood group. The following genotypes were found: 1,600 MM 250 MN 150 NN Calculate the observed genotype frequencies and expected genotype frequencies under Hardy–Weinberg equilibrium to fill in the blanks to the following questions. Remember to put a zero in front of the decimal point (e.g. 0.47) and round to the significant digits suggested. The observed genotype frequencies (use to 3 significant digits) are: MM = MN...
The occurrence of the NN blood group genotype in the US population is 1 in 400, consider NN as the homozygous recessive genotype in this population. You sample 1,000 individuals from a large population for the MN blood group, which can easily be measured since co-dominance is involved (i.e., you can detect the heterozygotes). They are typed accordingly: BLOOD TYPE GENOTYPE NUMBER OF INDIVIDUALS RESULTING FREQUENCY M MM 490 0.49 MN MN 420 0.42 N NN 90 0.09 Using the...
3) Your parents' generation has 80MM, 240MN, and 180NN individuals in each genotype for the M & N blood group. Your generation (siblings, cousins, yourself) has 15 MM, 11MN, and 24 NN individuals. Is your generation in Hardy-Weinberg Equilibrium with your parents? 4) There is a place where blue and white squirrels live. The blue allele (B) is dominate over the white allele (w) and has a frequency of 0.8. That is, B -0.8. In a population of 100 individuals,...
Find the calculations for the data of this population? a) Calculate the relative fitness for each of the three genotypes? b) What is the mean fitness of this population, and how do you expect it to change in response to selection? c) Based on the calculations in a), calculate the values of h and s. What type of selection has occured? d) If the surviving individuals mate at random, what will be the genotype frequencies in the next generation (...
This is Population Genetics. 6.11. Calculate the equilibrium allele frequency (9-) for each of the following fitness sets. Assume 110° in each case. What is the effect of partial dominance on the mutation-selection equilibrium? Explain in biological terms. (hint: use dominance model for fitness, 1. l-hs, 1-5) WI 1 0 .95 10.90 0.9 0.9 0.98 0.99 098
5 Suppose that you have a large population (>100,000 individuals). At a neutral locus in this population, the allele frequencies are freq(A1) = 0.25, freq(A2) = 0.75. You sample that population to form 100 sub-populations of 20 individuals each. Over the next 40 generations, all these sub-populations go to fixation at that locus. Approximately how many go to fixation for allele A1 vs. allele A2? 75 at A1, 25 at A2 50 at A1, 50 at A2 25 at A1,...
I posted this question before but no answer I need to submit in 4 hours, please help. Although the following scenario is hypothetical, it is based on actual facts. Sickle cell anemia is an inherited form of anemia. Those with sickle cell anemia do not have enough healthy red blood cells to adequately carry oxygen to all the cells in their body. Normal red blood cells are flexible and round, and can easily move through the blood vessels. However, in...
Question 9 1 CHOOSE THE BEST ANSWER FOR EACH QUESTION In a single lake, you observed that in shallow water, smaller fish have higher fitness because they can avoid predation from predatory birds, while in deeper water, large fish have higher fitness because they have more mating opportunities. What type of selection is currently occurring in this population of stickleback fish? [Select] Diversifying selection Stabilizing seleciton Directional selection for larger fish Directional selection for smaller fish datory birds are predicted...
