Question 3

Biological Species Concept

Answer 3

A group of organisms that freely interbreed to produce fertile offspring

Question 4

New Species Definition

Answer 4

A group of organisms with similar characteristics that are potentially capable of interbreeding to produce fertile offspring
A group of organisms in which genes can flow between individuals

Question 5

Mate Recognition Model

Answer 5

Based on unique fertilisation systems
Mating Behaviour

Question 6

Genetic Model

Answer 6

Based on DNA Evidence

Question 7

Evolutionary Model

Answer 7

Based on shared evolutionary relationships between species

Question 8

DNA Profiling

Answer 8

Process of which coding areas are analysed to find patterns
1) PCR to amplify the DNA
2) Gel Electrophoresis
Separates DNA fragments by length
Shorter fragments move at faster rates towards +ve anode
3) Stain it- Can see DNA under UV light

Question 9

Advantages of DNA Profiling

Answer 9

Can see a complete set of an organisms DNA

Question 10

Disadvantages of DNA Profiling

Answer 10

DNA samples can degrade over time

Question 11

DNA Barcodes

Answer 11

Each organism has its own barcode
Can be compared to another organism for classification
Used for pest control + food production

Question 12

Bioinformatics

Answer 12

Used to decipher human genome
Can predict potential drug side effects
Can make personalised medicine
Compares genetic information with that found in biological databases

Question 13

Peer Review

Answer 13

When biologists complete a study they write it in the form of an article which can be published
It will be read by other biologists who will test the validity of the results
If repeatable results can be made the findings are valid
