Question

Please help me about question c)!!!

1. The table below shows the genotypic frequencies of A/A, A/a and a/a individuals in three human populations. "A" and "a" are two alleles of a gene coding for a protein involved in brain development (specifically, the trigeminal nerve). People who are heterozygous or homozygous A/A have one or more symptoms related to ACHOO syndrome, a very common condition whereby a person has the urge to sneeze upon sudden exposure to bright light (you may have ACHOO too!). Population # Frequency of A/A 0.33 1.00 0.04 Frequency of A/S 0.34 0.00 0.32 Frequency of a/a 0.33 0.00 0.64 a) For each of the populations below, calculate the frequency of allele "A" and allele "a". b) Determine which of the populations is/are in Hardy-Weinberg equilibrium, showing all your calculations. c) A dictatorial government with a constantly sneezing leader takes power in the country where Population 1 lives. Under the new regime, people who do not have ACHOO syndrome (that is, the a/a individuals) are considered non-human and are deported to an isolated tropical island, and no a/a individuals are allowed into the country. What will be the allele and genotypic frequencies in the remaining (non- deported) population? ii) Will this population be in Hardy-Weinberg equilibrium? Show all your logic. d) After the departure of the a/a individuals, the remaining members of Population 1 are very concerned about potentially having a/a children. If they mate randomly with respect to A/A vs. A/a genotype, what proportion of the next generation will be homozygous recessive?

Answer 1

Ans:- 10) As ala individuals don't have 1CH00 syndrome are deported, and populafton , cives, Population 1,2% 3 are non- deported Allele will be A/a. Genotypic frequencies on 1 + "0.34 2 $ 0.00 3 0.32 ii) As Hardy- Weinberg principle states that the allele & genotype frequencies in a population will kema's constant from genecation to generation in the absence of other evolutionary influences. Ise this population will be in Hardy- Weinberg equilibricem.
