Identify a form of selection that maintains genetic variation in a population by establishing an equilibrium allele frequency between 0 and 1?
Identify a form of selection that, given sufficient number of generations and consistent environment, can result in the elimination of genetic variation in a population at a targeted gene locus _______
Identify a form of selection where the fixation of a single allele is the modeled outcome but which allele becomes fixed is dependent on the starting allele frequency conditions _______

1. Genetic variation _____. A. is created by the direct action of natural selection B. must be present in a population before natural selection can act upon the population C. arises in response to changes in the environment D. tends to be reduced by when diploid organisms produce gametes 2.

In the case of directional selection, if the advantageous allele (b) is recessive and a less advantageous allele (B) is dominant: A. b will be lost in the population because the dominant allele will increase in frequency by natural selection B. b will increase in frequency at the same speed as if it was a dominant advantageous allele, because what matters is the coefficient of selection and not if the allele is dominant or recessive C. b will increase in...

In a population of mice a particular locus has two alleles A1 (dominant) and A2 (recessive). There are 126 A1A1, 167 A1A2 and 88 A2A2. Is this population in Hardy-Weinberg equilibrium (3 pts)? In a population of Gragons, there are 3151 A1A1, 1678 A1A2 and 2014 A2A2 individuals. If the environment changes so that the homozygous recessive genotype suffers a reduction of fitness where its fitness is now 0.73, but the other genotypes are unaffected, what will be the frequency...

1a) Suppose a population of guppies was infected with a
parasite. In that population a mutation results in a parasite
resistant genotype that spreads through the population through
natural selection. A subsequent mutation in the parasite results in
a genotype that is unaffected by the newly evolved resistant guppy
genotype. What is the name of the hypothesis that explains this
host parasite “arms race”.?
