u are examining a scorpion population within the Las Vegas area. Your field team is able to capture 200 yellow scorpions and 450 brown orpions. You know that the color brown (B) is dominant over the color yellow (b). Based on this information, please answer the following estions. Be sure to show your work. - What is the allele frequency of each allele? • What percentage of scorpions in the population are heterozygous?

A population of frogs consists of 1000 individuals of which 400 are red. Red is recessive to Green. What is the frequency of the dominant allele and the recessive allele in this population? What is the frequency of individuals with homozygous dominant phenotypes? Please answer and show all work, thank you!! :)
I would like to get some help with Question #7 of this Problem Set: Researchers studying beach mice in Florida observed a population and were able to determine the number of individuals of each genotype (Table 1). Table 1. Observed numbers of beach mice with light and dark fur Question 7:
In a population of 500 fruit flies, 250 are genotype RR, 100 are genotype Rr and 150 are genotype rr. Determine the allele frequencies for this gene in this population. Remember that the frequencies should add to 1. Please show your work.
A 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).
You observe some bark beetles with different feeding behaviors. You find that the behavioral phenotypes you observed are closely associated with the following genotypes. genotype phenotype number observed BB feeds under bark 60 Bb feeds on top of bark 24 bb feeds on leaves 16 a) What are the allele frequencies and the expected number (out of 100 beetles) of genotypes? b) Calculate the Chi-Squared value (c2). Then look up the p-value using this Chi-squared calculator: https://www.mathsisfun.com/data//chi-square-calculator.html Enter “1” for Degrees of Freedom. (There are 3 genotype categories, but only 1 DF because they are not fully independent—calculated from just 2 allele frequencies). The p-value is the probability that you would see the deviance you observed by chance, assuming the null hypothesis is true). Report both values. Is the population in H-W equilibrium? c) If you answered “No” to b): Provide at least three biologically…
In a particular species of flower, C1 codes for red flowers, C2 codes for white, with the heterozygous individuals being pink. A. In the frequency of pink individuals in the population was .7126, would you be able to estimate the frequencies of the individuals alleles in the population? Why or why not? B. If the frequency of red individuals in the population was .329, what would the estimated frequency of pink and white individuals be in the same population?
Give only typing answer with explanation and conclusion In a class of 13 students, 2 had type A blood, 4 had type B, I had type AB, and 6 had type O. Assuming that this population is in Hardy-Weinberg equilibrium, calculate the frequencies of the three alleles (IA, IB , i )
In a population of millipedes, the gene “R” determines their color. The color red is determined by the dominant “R” allele and the color orange is determined by the recessive “r” allele. A population of 100 millipedes consists of the following genotypes: 30 RR 44 Rr 26 rr Answer the following - You can represent the ratio/frequency as a fraction or a %. A. What is the genotypic ratio of this population of millipedes? B. What is the phenotypic ratio of this population of millipedes? C. What are the allele frequencies for “R” and “r” in this population of millipedes?
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 a certain population of frogs, 120 are green, 60 are brownish green, and 20 are brown. The allele for brown is denoted GB, and the allele for green is designated GG. These two alleles are incompletely dominant to each other. If this population were in Hardy-Weinberg equilibrium, how many green frogs would you expect to observe? (Remember to multiply the expected frequency by the number of frogs in the population.)
