In a population of beetles carapace color is determined by a single gene with two alleles: Beetles homozygous for one allele have brown bodies; homozygotes of the other allele have green bodies; heterozygotes have green bodies with brown spots. In a sample of 1000 beetles there were 240 brown, 40 green, and 720 green with brown spots. Is this population in genetic equilibrium with respect to the gene for body color? O Yes, because the expected genotype frequencies sum to 1. O Yes, because the allele frequencies sum to 1. O No, there are more homozygotes than expected. O There is not enough information to determine. O No, there are more heterozygotes than expected. O Yes, observed and expected phenotypes are the same.

How Can We Measure Allele Frequencies in Populations? Drawing on your newly acquired understanding of the HardyWeinberg equilibrium law, point out why the following statement is erroneous: Because most of the people in Sweden have blond hair and blue eyes, the genes for blond hair and blue eyes must be dominant in that population.
How Can We Measure Allele Frequencies in Populations? The MN blood group is a single-gene, two-allele system in which each allele is codominant. Why are such codominant alleles ideal for studies of allele frequencies in a population?
In corn, yellow kernel color is governed by a dominant allele for white color, W, and by its recessive allele, w, . A random sample of 100 kernels from a population that is in equilibrium reveals that 9 are yellow and 91 are white. What are the frequencies of the yellow and white alleles in this population? What is the percentage of the heterozygotes?
A scientist is studying a wild population of Japanese morning glories. It is easy to separate genotypes at a flower color locus by their phenotypes. Red individuals are homozygous for the R allele, yellow individuals are homozygous for the Y allele, and orange individuals are heterozygous. If the number of individuals with the following genotypes are: RR: 831 RY: 33 YY: 442 Is the population in Hardy Weinberg Equilibrium?
In smurfs, blue tails and red tails are codominant to white tails (this is similar to blood type in humans). In a population of 200 smurfs, 6 have white tails, 93 have blue tails, 51 have red tails, and 50 have purple tails. Papa smurf has learned that the frequency of the blue tail allele is 0.53. Is this population in Hardy-Weinberg Equilibrium? Be sure to do a Chi-square test and show your work.
In hamsters, there is a dominant allele (S) for smooth fur and a recessive allele (s) for spiky fur. A unique characteristic of these alleles is that the heterozygote (Ss) has its own phenotype - rough fur. In this way, we can determind the number of heterozygotes in the population. In a population of 1000 hamsters, 390 have smooth fur (SS), 470 have rough fur (Ss) and 140 have spiky fur (ss). Question: The frequency of s (q) is equal to Question 1 options: 0.625 0.375 0.140 0.280

Color in a species of minnow is determined by a single locus with two alleles: D and d. DD individuals are dark, Dd are intermediate, and dd are pale. In a population that is in Hardy–Weinberg equilibrium, we count 74 pale minnows out of 202. How many minnows do you expect to be dark?
Cystic fibrosis is a genetic disease mostly affecting people of European descent that is caused by a recessive allele. You sample 1000 people for this allele and find 772 homozygous normal individuals, 221 heterozygotes, and 7 people homozygous for cystic fibrosis. Is this population in Hardy-Weinberg equilibrium?
A hypothetical species of plant has flowers whose color is controlled by a single gene with two alleles, blue (B) and yellow (Y), where blue is dominant and yellow is recessive. A population of 2430 of these plants includes 190 plants with yellow flowers.Assuming that the population is in Hardy-Weinberg equilibrium, what is the frequency of the yellow allele?
Which of the following statements would be true of ahuman trait that has high heritability in a populationof one country?a. The phenotypic difference within monozygotic twinpairs would be about the same as the phenotypic differences among members of dizygotic twin pairs.b. Very little phenotypic variation exists betweenmonozygotic twins but high variability exists between dizygotic twins.c. The trait would have the same heritability in a population of another country
