1.
Selective breeding is also known as:
Natural selection
Genetic modification
Artificial selection
Cloning
2.
A disadvantage of selective breeding is:
It increases genetic variation
It reduces the gene pool
It is very fast
It needs no parents
3.
Inbreeding increases the chance of:
Two harmful recessive alleles being inherited together
New mutations
Greater variation
Faster growth
4.
Which is an example of selective breeding in animals?
Inserting the insulin gene into bacteria
Breeding cows for high milk yield
Micropropagation
Producing Dolly the sheep
5.
Which statement best describes Artificial selection?
Another name for selective breeding, where humans rather than nature choose which organisms reproduce.
Humans choosing organisms with desirable characteristics and breeding them together over many generations to produce offspring with those characteristics.
The ability of an organism to avoid being harmed by a particular pathogen.
Breeding closely related individuals, which reduces genetic variation.
