b6b- inheritance: variation and evolution

Question 1

Genome definition

Answer 1

Entire genetic material of that organism

Question 2

Phenotype definition

Answer 2

The characteristics you have

Question 3

Mutation definition

Answer 3

a change in a chromosome/gene

Question 4

What is selective breeding?

Answer 4

A process in by which humans breed plants and animals for particular genetic characteristics

Question 5

What is genetic engineering

Answer 5

A process which involves modifying the genome of an organism by introducing a gene from another organism to give a desired characteristic

Question 6

Natural selection steps (4)

Answer 6

Individual organisms within a particular species show a wide range of variation for a characteristic and this variation is because of differences in their genes
animals will compete creating a struggle for existence
individuals with characteristics most suited to the environment are more likely to survive to breed successfully
The characteristics that have enabled these individuals to survive are then passed on to the next generation
