Two alleles (Adh' and Adh') of the Alcohol Dehydrogenase (ADH) gene exist in a large randomly-mating population of Drosophila
Two alleles (Adh' and Adh') of the Alcohol Dehydrogenase (ADH) gene exist in a large randomly-mating population of Drosophila. Researchers have determined the genotypes of the flies using gel electrophoresis. The number of individuals exhibiting all of the possible genotypes are listed in the table below. What are the allele and genotype frequencies for this population with respect to the Adh locus (please round to 2 decimal places)?
Effects of Inbreeding
Suppose that the population on the previous page is experiencing inbreeding depression (F=.05). Calculate the expected genotype frequencies in this population after one round of inbreeding.

In a large random mating population of plants, 16,800 individuals express the phenotype of the dominant allele (genotypes AA and Aa) and 3200 express the phenotype of the recessive allele (genotype aa). a. What are the frequencies of the two alleles in this population? b. How many plants would be expected to heterozygous? c. You decide to select for the recessive phenotype and pull up 50% of the plants expressing the dominant phenotype. What will be the gene frequencies of...

Consider two genes in a large, randomly mating population of turtles with no movement of individuals in and out of the population and no mutation. The two alleles at one gene, L and M, do not affect fitness. The two alleles at the other gene, T and t, do affect fitness -- they affect the thickness of turtle shells, and the degree to which they are protected from predation. TT individuals have thick shells, which repel predators, and survive best....

1. A particular gene in a given population of individuals has two alleles, A and a. The frequency of the A allele equals the frequency of the a allele. What are the expected genotype frequencies, assuming the population is in Hardy-Weinberg equilibrium? AA = 0.5, aa = 0.5 AA = 0.25, Aa = 0.50, aa = 0.25 O A = 0.5, a = 0.5 The answer cannot be determined because the allele frequencies are not provided.

The knobcone gene has two alleles that segregate within a population of loblolly pine. In this population of loblolly pine, you observe two genotypes with frequencies of 0.75 and 0.25. The fitness of the genotype with a frequency of 0.75 is equal to 1.0, whereas the fitness of the other genotype is 0.8. What is the mean fitness at this locus within this population? Answer: The answer is 0.95. I'm not sure how to get there
