Homework Answers
Answer :-
The frequency of alleles always change over time because Natural selection, genetic drift, and gene flow are the mechanisms that cause changes in allele frequencies over time.

Select the statements that accurately describe the effect of natural selection on genetic equilibrium: a. It can cause allele frequencies in a population to be in genetic equilibrium. b. It can cause a dominant allele for a gene to become more abundant in a population. c. It can cause an allele to become more abundant in a population if it provides a fitness advantage over other alleles for that trait. d. It is an evolutionary force that prevents natural populations...

Select all of the statements about genetic drift that are true. It can cause alleles to be lost in a population by chance. Genetic drift causes allele frequencies to change because only the strongest individuals in a population are reproducing Its strength is proportional to the size of a population -the larger the population, the greater the force Smaller populations experience greater changes in allele frequency due to genetic drift than large populations. It is a random process with respect...

Which of the following statements regarding the Hardy-Weinberg Equation is TRUE? Answers: It can only be used when allele and genotype frequencies remain constant across generations in a population It can only be used when allele and genotype frequencies change across generations in a population It has no assumptions It mathematically shows how recessive alleles in a population decrease over time It reveals when allele frequencies change over time in a population Assuming Hardy-Weinberg Equilibrium, what percentage of individuals in...

1. Which of the following is FALSE? A. If a genetic disease reduces fertility and the allele that causes the disease offers no other advantage, the allele will likely eventually disappear, due to natural selection. B. Natural selection does not favor individuals who are homozygous for the sickle-cell allele, because these individuals typically die before they are old enough to reproduce. C. Individuals who are heterozygous HbA/HbS are protected from malaria, and this is why sickle-ce disease persists in wetter,...

Which condition can lead to two populations becoming different species? all of these A barrier to gene flow exists between the two populations. Individuals in the two populations have significant genetic differences from one another. Individuals may live in geographically isolated areas. Individuals in the two populations mate at different times. Which of these is NOT an example of adaptive evolution? bottleneck all of these gene flow founder effect Mutation Which of these does NOT influence allele frequencies in a...
