Androgenetic alopecia (pattern baldness) is a complextrait in humans governed by several genes, but supposea human population exists in which a single autosomalallele determines pattern baldness. This allele is dominant in males and recessive in females. The population is in Hardy-Weinberg equilibrium, and 51% ofthe men are bald.a. What is the allele frequency of the baldness alleleamong males?b. What is the allele frequency of the baldness alleleamong females?c. What percentage of the women in this populationwill exhibit pattern baldness? d. Assuming random mating, what proportion of allmatings should be between a bald man and anonbald woman?e. What percentage of the bald men in the populationare heterozygotes?f. If a nonbald couple produces a bald son, what isthe probability that their next son will be bald?g. A woman with androgenetic alopecia has a daughter, but nothing is known about the father. What isthe probability that the daughter will be bald?
Evolutionary Genetics
Evolution is known as continuous changes that occur to adjust organisms in their changing environment over many generations. Various theories have been proposed to illustrate the origin of life and organic evolution. The most accepted one is the theory of natural selection by Charles Darwin. According to his postulate, organisms undergo a struggle for existence due to overproduction. To survive in nature, they acquire variations. The inheritable variations are selected by nature, and it leads to the survival of the fittest.
Phenotype Frequency
The majority of populations have a certain degree of variation in their genetic pools. Scientists can predict the genetic variation happening over time by measuring the amount of genetic variation in a population and these predictions assist them in gaining important insights into the processes that allow organisms to adapt to the environment or to develop into new species over generations. This process is referred to as the process of evolution.
Hardy Weinberg Equilibrium
The frequencies of allele and genotype were maintained constant from one generation to another due to the absence of other evolutionary forces. It is otherwise called the Hardy Weinberg principle the field of population genetics.
Androgenetic alopecia (pattern baldness) is a complex
trait in humans governed by several genes, but suppose
a human population exists in which a single autosomal
allele determines pattern baldness. This allele is dominant in males and recessive in females. The population is in Hardy-Weinberg equilibrium, and 51% of
the men are bald.
a. What is the allele frequency of the baldness allele
among males?
b. What is the allele frequency of the baldness allele
among females?
c. What percentage of the women in this population
will exhibit pattern baldness? d. Assuming random mating, what proportion of all
matings should be between a bald man and a
nonbald woman?
e. What percentage of the bald men in the population
are heterozygotes?
f. If a nonbald couple produces a bald son, what is
the probability that their next son will be bald?
g. A woman with androgenetic alopecia has a daughter, but nothing is known about the father. What is
the probability that the daughter will be bald?
