Question 1

What is a genetic variant?

Answer 1

• when mutations become established in population
• If advantageous it can be slected for(natural selection)-useful for survival

Question 2

What is a mutation?

Answer 2

• Change in your DNA code
• DNA triplet codes look like:ATG, TCG,GGT and so on, only includes A,T,C,G

Question 3

What is adaptation?

Answer 3

• This is when a characteristic makes an organism more likely to survive and reproduce
• Happens when a mutation takes place

Question 4

What is natural selection?

Answer 4

• Natural selection is a process where organisms that are better adapted to an environment will survive and reproduce
• Happens when a random mutation in DNA creates a new genetic variant in a population
• If advantageous it increases the likelyhood of the surviving of the organism and the reproduction

Question 5

What is selective breeding?

Answer 5

When individuals with desirable characteristics are selected and bred together to product an offspring with desirable characteristics

Question 6

What is evolution?

Answer 6

• The process of natural selection
• Can lead to speciation
• Populations become different over time due to different selction pressures(competition)

Question 7

What is asexual reproduction and sexual reproduction?

Answer 7

• Asexual production is when a species reproduces by itself, less variation but can mutations
• Sexual production when a species needs two parents to reproduce, more variarion

Question 8

What is biodiversity?

Answer 8

A combination of the diversity of living organisms, their genes and the ecosysten in which they live.

Question 9

What is food security?

Answer 9

being able to produce enough food for the human population to survive
