Question

When migration is happening between 2 populations, can these populations be in Hardy-Weinberg Equilibrium?

A. No, neither population is in HWE

B. Yes, both populations are in HWE

C. Yes, just one of the populations is in HWE

Answer #1

Answer: A. No, neither population is in HWE.

The hardy.Weinberg equilibrium if a population is not evolving or getting disturbed by any factor like mutation, gene flow, random mating etc the genetic variation will remain constant. If there is a migration between two population then the size of the population changes and also the gene and the mating which will lead to the disturbance in the existing equilibrium and maybe the generation of new equilibrium considering two population as one.

How can evolutionary biologists use Hardy-Weinberg equilibrium
while studying populations of organisms that they suspect may be
evolving?

Which of the following situations is in Hardy–Weinberg
equilibrium?
A. A small number of fish can be found in a man-made pond at
Hawrelak Park.
B. In a large population of E. coli bacteria, some are
demonstrating resistance to penicillin.
C. Biosphere 2 is a closed ecological system located in
Arizona.
D. An isolated population of caribou has been found on Baffin
Island.

Explain why we use the concept of Hardy-Weinberg Equilibrium if
populations are never stable. What do the mathematical results tell
us if the allele frequencies do not match our predictions? (In
other words, if you have extra spotted fish in a generation, what
has happened?)

Explain the key purpose of the hardy weinberg equilibrium
frequencies. What could the calculations do for a scientist who is
interested in some gene or genes in a species beyond/in addtion to
just giving you the frequency of genotypes or alles of those genes
in a population?

If a population is growing exponentially and while doing
so, also remains in Hardy-Weinberg equilibrium, name two things
that will not change about this population from generation to
generation.
A.
B.
Given this situation, what is something that definitely
will change from one generation to the next?
A.

Can very rare alleles exist in
Hardy-Weinberg equilibrium? (i.e. frequencies of 1
in 100,000 or less)? Explain briefly.

1. Explain how sexual recombination generates genetic
variability
2. List the five conditions of Hardy-Weinberg equilibrium
3. Apply the Hardy-Weinberg equation to a population genetics
problem
4. Explain why natural selection is the only mechanism that
consistently produces adaptive
change
5. Explain the role of population size in genetic drift
6. List four reasons why natural selection cannot produce
perfect organisms

A population of 100,000 Arabidopsis thaliana plants is initially
at Hardy-Weinberg equilibrium for the A gene, where two alleles, A1
and A2, are present at equal frequencies. The population undergoes
2 generations of 100% self-fertilization. a) After 2 generations of
selfing, what are the expected values for: 1) genotype frequencies,
2) allele frequencies, and 3) the population inbreeding
coefficient. (The math is easiest using fractions.)

The Hardy–Weinberg principle states that allele and genotype
frequencies remain constant from one generation to the next, as
long as specific conditions are met.
Write Yes or No for the conditions that must be met from the
provided statements.
Mutations
are exponentially occurring.
All
members of the population breed.
Everyone
produces the same number of offspring.

In a Hardy-Weinberg population with two alleles, T and
t, that are in equilibrium, the frequency of the allele
t is 0.3.
Therefore [ Select ]
["p^2",
"p", "q", "q^2"] = 0.3
What is the percentage of the population that
is Homozygous dominant (TT) for this
allele? [ Select ]
["70", "0.7", "49", "0.49"]
What is the percentage of the population that...
