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.

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

True
False
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
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

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
Dissasortative mating
Rapid reduction in population size
Self-fertilization
Selection of mates based on geographic proximity
Genetics
Initial frequency of the allele
The strength of selection
Ratio of males to females
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
Selection for advantageous alleles

True
False
Coalescent theory
Neutral theory

Sexual selection
Purifying selection
Genetic drift
Frameshift disquilibrium
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
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
