The following are the observed ABO blood group phenotypes among a group of Canadian Indians: O A B AB , 288 280 19 13 , respectively. Compute for the gene frequencies.
Tay-Sachs disease in humans is caused by a recessive allele. The disease is characterized by mental deficiency and blindness, with death occurring by 4 years of age. Among
Ashkenazi Jews of central European ancestry, about 1 in 3600 children is born with the disease. Assume Hardy-Weinberg equilibrium and calculate the frequency of the Tay-
Sachs allele in this population. Round your answer to the nearest 0.001.

You study a population of California kingsnake (Lampropeltis getulus californiae). There are two color patterns
in the population (banded and striped). This pattern is controlled by one gene. You genotype 150 snakes.
Your results are in the table below. Use these data to answer the following questions.
Part A: What are the population's observed genotypic frequencies?
Part B: What are the allelic frequencies for this gene?
Part C: What are your expected genotypic frequencies?
Part D:Is this gene in H-W equilibrium? Offer a theory about why it is or is not.

- 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).

- A study on blood types in a population found the following genotypic distribution among the people sampled: 1101 were MM, 1496 were MN and 503 were NN. i) calculate the allelic genotypic frequencies. ii) using x² test, determine whether or not this population is in Hardy-Weinberg equilibrium. Important information from the x² distribution is given in the picture attached.arrow_forwardHere, N₁ is the number of fish with genotype II, N₁c the number with genotype lc, and Ncc the number with genotype cc.

DNA from the crime scene was analysed and yielded the following SNP genotype: A1A2, G2G2, T1T2 for both the victim and a suspect.
