Concept explainers
a.
To explain: The term population.
Introduction: The hierarchal system of classification classifies and groups the living organisms into different level based on the characteristics and properties they have in common. The basic unit of classification in this system is the species.
b.
To explain: The term gene pool.
Introduction: A gene can be defined as a unit of inheritance which enables the transfer of characteristics from the parent to its offspring. It helps in the transmission of characteristics across generations.
c.
To explain: The term allele frequency.
Introduction: Allele refers to a pair of genes present on a chromosome. The allele is responsible for propagation of traits in organisms. Alleles are generally present in pairs of two.
d.
To explain: To explain the term genotype frequency.
Introduction: Genotype can be described as the genetic constitution of an individual. Genotype constitutes of the genes which underlie the inheritance amongst organisms.

- How Can We Measure Allele Frequencies in Populations? What are four assumptions of the HardyWeinberg law?arrow_forwardPopulation genetics is the study of: a. how selective forces change the allele frequencies in a population over time b. the genetic basis of population-wide traits c. whether traits have a genetic basis d. the degree of inbreeding in a populationarrow_forwardAlbinism is due to a recessive allele of an autosomal gene. Let a represent the albino allele and A represent the normal non-albino allele. If one out of every 10,000 people were albino and assuming that the population is in Hardy-Weinberg equilibrium, A. what would be the phenotype frequencies of albino and non-albino ? B. what would be the allele frequencies of a and of A? C. what fraction of people can be expected to be of the genotype Aa? D. what fraction of people can be expected to be of the genotype AA?arrow_forward
- Two populations of antelope are separated by a mountain range. The antelope are known to occasionally migrate from one population to the other. Migration can occur in either direction. Explain how migration affects the following phenomena: A. Genetic diversity in the two populations B. Allele frequencies in the two populations C. Genetic drift in the two populationsarrow_forwardYou are surveying population genetics of snails while studying abroad in New Zealand. At your locus of interest, you have AA: 32 Aa:46 aa: 22. Identify the statement that accurately describes this population. a. The genotype frequency of AA is 0.77. b. The frequency of the A allele is 0.45. c. The genotype frequency of the heterozygotes is 0.45. d. The frequency of the a allele is 0.23.arrow_forwardWhat are some general tips in calculating allele and genotype frequencies? Examples of each will be useful.arrow_forward
- A particular deer population has 50 M individuals, 30 MN individuals, and 70 N individuals. What are the allele frequencies?arrow_forwardBelow are individuals in a population broken down by genotype. (A) Complete the table AA Aa aa Total # individuals 305 650 55 # A alleles # a alleles (B) Determine the frequency of alleles A and a. Show your work. (C) Assuming the population is in Hardy-Weinberg equilibrium, determine the number of heterozygous individuals in the next generation with a population of 1200.arrow_forwardA mountain region has a population of 5,000 mountain goats. You score these animals for the R locus and find that this locus has two alleles, R (dominant) and r (recessive). 3200 individuals are homozygous dominant, 1,600 are heterozygous, and 200 are homozygous recessive. a) Calculate the allele frequencies for this population. Show your work. b) Calculate the observed genotypic frequencies for this population. Show your work. c) Calculate the expected genotype frequencies if the population is in Hardy-Weinberg equilibrium. Show your work. d) Does this population appear to be at H-W equilibrium? Why or why not? (You do not need to analyze this statistically).arrow_forward
- A population of birds may have red feathers or orange feathers. Red feathered birds have the genotype RR or Rr. Orange feathered birds have the genotype rr. The frequency of the RR genotype is .46 a. What is the frequency of heterozygous birds? B. What is the frequency of the R allele ? C. What is the frequency of r allele?arrow_forwardA population is made up of individuals where 77 have the A1A1 genotype, 65 have the A1A2 genotype, and 123 have the A2A2 genotype. What is the allele frequency of A1? Answer to 2 decimal places.arrow_forwardAssume we are examining one gene with two alleles, a dominant (p) allele and a recessive (q) allele. if a population starts with individuals as follows: 140 homozygous dominant, 40 heterozygous, and 20 homozygous recessives. What are the allelic frequencies for this population?arrow_forward
