Unit 5: Classification and Evolution

 

Genetic drift is change in the allele frequency of a population due to...

• random chance

• natural selection

• non-random mating (sexual selection)

• artificial selection

 Genetic Drift is more likely to happen in... 

• aquatic populations

• small populations

• terrestrial populations

• older populations

All of the genetic information found in a population

• population

• genetic drift

• evolution

• gene pool

A change in a gene, group of genes or chromosome that results in a change in the proteins

• Replication

• Mutations

• Translation

• Transcription

A mutation is defined as:

• A change in the cell's structure

• Anything that changes in an embryo

• Any change in the physical features of a human

• A change in the DNA sequence

Genetic drift is driven by chance, not Natural Selection.

• false

Maria Concepcion Soto settled in the northern area of Venezuela. She suffered from a rare genetic disorder called Huntington’s Disease. As a result, the now 20,000 individuals who live there also have a high risk of Huntington’s Disease.

• Gene flow

• Genetic Drift

Genetic Diversity is increased through this process.
