Over time, different scholars have come up with different theories to describe the origin of man. The quiz below specifically focuses on the Biological change in the heritable characteristics of man. All the best and enjoy.
The non-Mendelian and often unpredictable interactions of alleles at different loci
The movement of genetic material from the nucleus to the organelles.
The change a population undergoes during a bottleneck event
The uneven distribution of alleles across a population
Rate this question:
True
False
Rate this question:
At the third position in codons because they have a higher mutation rate
At the third position in codons because these mutations are most often neutral and not subject to purifying selection
At the second position in codons because they have a higher mutation rate
At the second position in codons because these mutations are most often neutral and not subject to purifying selection

Rate this question:
Most bacteria cells are much smaller than eukaryotic cells
Eukaryotic organisms have large majorities of their genome that are non-protein coding

Translational bias due to non-random distribution of tRNA isoforms
True
False
Rate this question:

1/2Ne
4Nµ
Rate this question:
A population of 14 humans isolated on a remote island with no contact with the rest of the human species
A nearly extinct species of seal with only 40 individuals remaining
A protozoan that can only reproduce asexually
A plant that is isolated from all other members of its species, but can still produce viable offspring via self-fertilization
Rate this question:
Coefficients of selection < 1/2Ne greatly reduce the Heterozygosity
High mutation rates greatly reduce the Heterozygosity
Recent bottleneck events greatly reduce the Heterozygosity
Random mating will greatly reduce the Heterozygosity
The percentage of a population that passes its genes onto the next generation
The complex interaction of alleles to produce unexpected phenotypes
The portion of a phenotypic trait that is due to genetics
The ability of a plant to influence the microclimates around them
Rate this question:
True
False
Rate this question:
Mistakes made during replication phase of mitosis of non-germ line cells
Mistakes made during transcription of DNA into mRNA
Mistakes made during translation of mRNA into proteins
Mistakes made during replication phase of meiosis
Rate this question:
All organisms have about the same mutation rate
Selection tends to favor organisms with very low mutations rates
Selection tends to favor organisms with very high mutation rates
Mutation is a hallmark of successful populations and different environments and life histories select for different mutation rates
Rate this question:
Aposematic coloration, such as the bright colors of poison dart frogs
A disadvantageous allele right next to an advantageous allele on a chromosome
Sneaker males, such as in some species of dung beetle
Sickle cell anemia in humans
Rate this question:
True
False

Rate this question:
There had been much more variation in the wind blown pollen that fertilized this population than in the seeds which do not disperse as far.
Heavy grazing by herbivores had selectively reduced the different varieties of mitochondria
Black spruces mitochondria are a relatively recent addition to their cells and have not had time to diversify
The mitochondria have a very low rate of evolution when compared to the nuclear genes
Rate this question:

ε, the average genetic load
Ne, the effective population size
Rate this question:
Many recent mutations
Entire genome found on one chromosome
Frequent crossing over events
Inbreeding depression
Rate this question:
If it was at Hardy Weinberg equilibrium.
Alteration of generations within a subset of the population.
A bottleneck event, which would increase the influence of genetic drift.
A rapid breakup of any linkage disequilibrium through crossing over events.
