In a population that is in Hardy Weinberg equilibrium, 49% of the individuals are recessive homozygotes for a certain trait. In a population of 5500, calculate the following:
a) The number of homozygous recessive individuals in the population
b) The number of heterozygotes in the population
In a population that is in Hardy Weinberg equilibrium, 49% of the individuals are recessive homozygotes...
In a hypothetical population which is in Hardy Weinberg equilibrium, the frequency for a recessive allele is 30%. What percentage of the population would be expected to show the dominant trait in the next generation? Humans who are born homozygous for the recessive sickle cell allele die of sickle cell anemia, while those who are heterozygous are resistant to malaria (see chapter 4 for more information on this balanced polymorphism). 4% of the population of the Congo are homozygous recessive for...
2. Hardy-Weinberg Equilibrium; chi-square test Sickle cell anemia is a recessive disorder caused by a recessive mutation (S) in the b-hemoglobin gene. 80% of affected SS individuals die before reproducing. Heterozygotes (AS) and homozygous dominant (AA) individuals do not have sickle cell anemia. The table below shows the number of people of each genotype in a population of 100 people in population of Cameroon. Observed # individuals in a Cameroon population AA AS SS 62 32 6 What are the...
Consider a sample of 100 individuals sampled from a population in Hardy-Weinberg equilibrium that are genotyped at a single locus. Of these 100 individuals, 25 individuals are A 1 A1 homozygotes, 45 are A 1 A 2 heterozygotes, and 30 are A 2 A 2 homozygotes. List the observed and expected genotypic frequencies of this locus in this sample. T TTArial 3 (12pt) T-
In a population that meets Hardy- Weinberg equilibrium assumptions, 81% of the individuals are homozygous for the recessive allele. What percentage of the individuals would be expected to be heterozygous for this locus in the next generation?
If individuals homozygous for a recessive mutation make up 16% of a population at Hardy-Weinberg equilibrium, the frequency of heterozygous individuals would be a. 84% b. 36% c. 24% d. 48% What percentage of the population are heterozygous? a. 42% b. 0.42 c. 97% d. 91% e. 94% If you sample diatoms Parisians 100 years from now, what should be the frequency of individuals with short antennae? a. 0.09 b. 0.91 c. 0.095 d. 0.03
EXERCISE 6 HARDY-WEINBERG EQUILIBRIUM Work in a small group or alone to complete this exercise. In human population X consider the simple Mendelian trait for freckles. F is the dominant allele and fis the recessive allele. Individuals who are homozygous dominant (FF) or heterozygous (F) for the trait express freckles. Individuals who are homozygous recessive (ff) for the trait do not express freckles. In this population, 30% (0.3) of the alleles are recessive (1) and 70% (0.7) are dominant (F)....
2.3 Problem 3 The Hardy-Weinberg equation is useful for predicting the percent of a hu- man population that may be heterozygous carriers of recessive alleles for certain genetic diseases. Phenylketonuria (PKU) is a human metabolic dis- order that results in mental retardation if it is untreated in infancy. In the United States, one out of approximately 10.000 babies is born with the disor- der. Approximately what percent of the population are heterozygous carriers of the recessive PKU allele? If you...
Assume that you have a population in Hardy-Weinberg equilibrium for a particular trait Within this population, what will be the proportion of matings between homozygotes?
Testing the goodness of fit between the data and the Hardy Weinberg equilibrium model generated expectations. 4.1 In a species of bird, feather color is controlled by genes at a single locus, with the red feather allele dominant to the yellow feather allele. A population has 22 red and 14 yellow birds, with 9 of the red birds having a homozygous dominant genotype. Is this population in equilibrium? Calculate p and q from the number of individuals of each genotype:...
2. Assume a population is in Hardy-Weinberg equilibrium for a given genetic autosomal trait. What proportion of individuals in the population are heterozygous for the gene if the frequency of the recessive allele is 1%.
