Hardy-Weinberg
What does the Hardy-Weinberg principle predict?
Allele and genotype frequencies will remain constant in a population if no evolutionary forces act on it.
The frequency of two alleles in a gene pool is 0.19 (A) and 0.81(a). Assume that the population is in Hardy-Weinberg equilibrium.
Calculate the percentage of heterozygous individuals in the population.
What is 31%
What is genetic drift?
A change in allele frequencies due to random chance
What is the hottest planet in the solar system?
Venus!
All genes of all members of a population make up it's...
What is gene pool
What are the five conditions required for Hardy-Weinberg equilibrium?
Large population, random mating, no mutations, no gene flow, no natural selection
An allele W, for white wool, is dominant over allele w, for black wool. In a sample of 900 sheep, 891 are white and 9 are black. Calculate the allelic frequencies within this population, assuming that the population is in H-W equilibrium.
What is the dominant allele = 0.9 and the recessive allele =.1
What is the founder effect?
Genetic drift that occurs when a small group colonizes a new area
This man came up with the idea for the periodic table and now has an element named after him.
Who is Dmitri Mendeleev?
What is speciation?
The formation of new species
Which Hardy-Weinberg condition would be the most difficult to maintain when studying a large population of worms in a lab?
No mutations
In a population that is in Hardy-Weinberg equilibrium, the frequency of the recessive homozygote genotype of a certain trait is 0.09. Calculate the percentage of individuals homozygous for the dominant allele.
What are is 49%
What is the bottleneck effect?
A sudden population reduction that changes allele frequencies
Which team LOST the 2016 Superbowl?
Double points if you can name the starting QBs from both teams
Carolina Panthers lost
Peyton Manning and Cam Newton were starting QBs
In a population the sum of all allelic frequency in a population must be...
What is 1 or 100%
Why is Hardy-Weinberg considered a "null model"?
It never happens in real life/is impossible to control for.
In humans, the Rh factor genetic information is inherited from our parents, but it is inherited independently of the ABO blood type alleles. In humans, Rh+ individuals have the Rh antigen on their red blood cells, while Rh− individuals do not. There are two different alleles for the Rh factor known as Rh+ and rh. Assume that a dominant gene Rh produces the Rh+ phenotype, and that the recessive rh allele produces the Rh− phenotype.
In a population that is in Hardy-Weinberg equilibrium, if 160 out of 200 individuals are Rh+, calculate the frequencies of both alleles.
What is Rh+ = 0.89 and rh = 0.11
What is sexual selection?

What the difference between natural selection and artificial selection (with an example)?
●Nature “selects” traits that are better suited for survival and reproduction
●Humans select traits that are desirable. Domestication of plants and animals
What is Hardy-Weinberg's Equation?
P2+2PQ+Q2=1
A rare disease which is due to a recessive allele (a) that is lethal when homozygous, occurs within a specific population at a frequency of one in a million. Specifically one-in-a-million individuals are born with the lethal disease.
How many individuals in a town with a population of 14,000 can be expected to carry this allele?
What is approximately 28 individuals
Why does non-random mating violate Hardy-Weinberg?
It leads to sexual selection- a type of evolution
