1
Q

Orthologs

A

Genes that can be traced to speciation events (genes found in different species)

2
Q

Paralogs

A

Genes that are related through duplication events (genes in same or different species)

3
Q

Concerted evolution

A

Species evolving together

4
Q

Unequal crossing over

A

Exchange of traits on a gene resulting in one gene with more traits then the other

5
Q

Biased gene conversion

A

Damage gene getting repaired resulting in the same as unequal crossing over

6
Q

Genetic drift

A

Change in allele frequency

7
Q

Stabilizing selection

A

Genetic diversity decreases but population stabilizes on a particular trait

8
Q

Founder effect

A

Loss of genetic variation when a new population is established by a small number of individuals from a larger population

9
Q

Homoplastic traits

A

Similar Traits created by convergent and evolutionary reversal

10
Q

Sequence alignment

A

Deletion and insertions in a genetic sequence

11
Q

Anaueploidy

A

Mistake in meiosis

12
Q

Synonymous substitution

A

Substitution (mutation) that doesn’t change the amino acid (also called silent substitution)

13
Q

Non synonymous substitution

A

Substitution that changes amino acid

14
Q

Pseudo genes

A

Copies of genes no longer functional that can serve for the creation of new genes

15
Q

In vitro evolution

A

Cells made in a lab for specific functions
