Evolution

Evolution

________ is the changes in organisms over generations as a result of genomic variations.

Horizontal inheritance

________ frequently involves the exchange of whole or parts of a plasmid.

Sympatric speciation

________ is brought about by behavioural or ecological barriers.

fertile offspring

A species is a group of organisms capable of interbreeding and producing ________, and which does not normally breed with other groups.

Natural selection

________ is the non- random increase in frequency of DNA sequences that increase survival and the non- random reduction in the frequency of deleterious sequences.

Prokaryotes

________ and viruses can also exchange genetic material between members of the same generation.

Allopatric speciation

________ occurs when populations become physically separated.

Speciation

________ is the generation of new biological species by evolution as a result of isolation, mutation and selection.

Inheritance

________ usually involves the passing of genetic material from parents to offspring.

Prokaryotes

________ usually reproduce by binary fission, a form of vertical inheritance.

Stabilising

In ________ selection, an average phenotype is selected for and extremes of the phenotype range are selected against.

Directional

In _________ selection, one extreme of the phenotype range is selected for.

Disruptive

In _______ selection, two or more phenotypes are selected for.
