What is the outcome of competition if K1 = 200, K2 = 150, α12 = 0.25, and α21 = 4? Include a graph to document your conclusion.

The following data for the genotypes at the alcohol dehydrogenase locus were observed from a sample of Drosophila melanogaster. Sample size 1000 FF 550 FF=0.55; FS=0.34; SS=0.11 O F-0.72; S=0.28 FF=0.078; FS=0.40; SS=0.52 FS What are the Hardy-Weinberg equilibrium genotype frequencies for each genotype based upon this sample? OFF=0.52; FS=0.40; SS=0.078 340 SS 110

The following gel represents a result of the RFLP experiment you designed using the DNA of 9 different individuals (this is your population). The ladder used is a 50bp ladder and is loaded in the first well.   1. What is the percentage of non-tasters in this population? 2. What is the percentage of heterozygous in this population? 3. What is the frequency of nontaster allele in this population? 4. What is the frequency of the taster allele in this population?

You sample a fruit fly (Drosophila melanogaster) population for the alcohol dehydrogenase (Adh) gene. There are two alleles, designated A₁ and A2, for this locus in this population. The data you collected is shown in this table (this is your observed data). Is this population in Hardy-Weinberg equilibrium at this locus? To save you time, I have calculated the expected number of individuals for each genotype and included them in the table. For your answer, you should provide: • an answer to the question: Is this population in Hardy-Weinberg equilibrium for this locus? • the value of your chi-square result you based this answer on (you do not have to show your calculations for the homework, but you would on an exam) • (if you say the population is NOT in HW equilibrium) an evaluation of which genotype(s) are more or less common than expected in the observed population # individuals genotype A₁A₁ # individuals genotype A₁A2 # individuals genotype A₂A2 154 117 Observed data Expected data…
