Use the Hardy-Weinberg equations (p2 + 2pq + q2 = 1 and p + q = 1) to find the genotypes of the following hypothetical phenotypic information:
a. Within a particular population, you observe that 450 individuals have freckles (dominant, F) and 550 do not have freckles (recessive, f).
b. Homozygous dominant (frequency) ______(A)_________
c. Heterozygous (frequency) ______(B)_____________
d. Homozygous recessive (frequency) _______(C)____________
Homework Answers
Answer:
Frequency of freckles = q^2= 550/1000= 0.55
Frequency of recessive allele =q= sqrt of 0.55= 0.74
Frequency of dominant allele= p=1- 0.74= 0.26
Frequency of Homozygous dominant= pp= 0.26*0.26= 0.07
Frequency of heterozygote =pq= 2*0.26*0.74= 0.38
Frequency of Homozygous recessive= 0.74*0.74= 0.55

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...
The Hardy-Weinberg principle and its equations predict that frequencies of alleles and genotypes remain constant from generation to generation in populations that are not evolving
.1. The Hardy-Weinberg principle and its equations predict that frequencies of alleles and genotypes remain constant from generation to generation in populations that are not evolving. What five conditions does this prediction assume to be true about such a population? a._______ b._______ c._______ d._______ e._______ 2. Before beginning the activity, answer the following general Hardy-Weinberg problems for practice (assume that the population is at Hardy-Weinberg equilibrium).a.

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)....
