How do you get a mutation in your DNA?
Slide 3 - Open question
mutations
= change in a gene or chromosome (genotype)
This may result in no/small/large change in phenotype
Slide 4 - Slide
mutations
= change in a gene or chromosome (genotype)
This may result in no/small/large change in phenotype
the change can be negative/neutral/beneficial
