Q

Why is genetic diversity important
And where does it come from

A

To create a more diverse economy and biodiversity

Through mutations/inheritance

Q

Example of population of a species go to two different species

A

Reproductive isolation where one species suddenly change its traits and type of mate maybe due to a transfer of location or limited diversity which the. Cause that species to develop changes Overtime

17
Q

3 types of speciation

A

Geographical
Behavioural
Temporal

18
Q

Geographic Isolation

A

Populations seperated by a barrier

19
Q

Behavioural isolation

A

Difference in behaviour which prevents them from reproduction

20
Q

Temporal

A

Populations which reproduce at different time of day and year

21
Q

3 evidence for scientific theory of evolution

A

Homologous
Vestigial

22
Q

Homologous and vestigial traits difference

A

Homologous are shared by different species based on a common ancestor

Vestigial are reduced remnants of a functioning structure due to change and adaptation

23
Q

Mass vs background extinction

A

Mass: short period
Back: occurs slowly

24
Q

Mutations and their importance in evolution

A

Changes in the DNA sequence of an organism however mutations can either help the organism survive through environmental sorrounding or help the organism due to changes and natural selection

25
How does genetic drift contribute to evolution
Changes in alleles or genetic variation could contribute to evolution through its changes and so creating a new species or evolution of a species it self to better survive and reproduce or the opposite
26
Speciation
When populations become different species when they experience reproductive isolation
27
Phylogeny
Refers to evolutionary history and relationships between different species or groups of organisms
28
Aerobic
Require oxygen
29
Anaerobic
Do not require oxygen
30
Seven levels to classification and organization
Domain Kingdom (kids ) Phylum (playing) Class (chicken) Order(on) Family (freeways ) Genus(gets) Species(smashed)
31
What was the first two groups developed
Animalia and Plantae
32
Who created the modern taxonomic system or is responsible
Carl Linnaeus
33
Dichotomous key
Identify organisms based on binary choices
34
What are the scientific name of chimpanzee and humans
Homo Sapiens Pan troglodyte
35
Taxa for humans
K: AnimaliA P: chordata C:mamalia O:primates F:Hominidae G:Homo s:sapiens
36
4 types of selection natural
Directional Stabilizing Disruptive Sexual
37
Directional selection
one of the extreme versions of a trait provide higher fitness
38
Stabilizing selection
Camouflage average
39
Disruptive
Whichever is better at catching prey both extreme leads to speciation
40
Sexual selected
Mating preferences
