Genetic Variation Flashcards
What are the 3 main sources of genetic variation
Mutation, gene flow & genetic drift
What are the 5 variants of mutation when it comes to genetic variation
Missense mutation, nonsense mutation, interion mutation, deletion mutation and duplication mutation
What is missense mutation of genetics
Change in single base pair - amino acid substitution
What is nonsense mutation when it comes to genes
Changes is base pair - prematurely Signals half to the construction of a protein
What is intertion mutation when it comes to genes
Changes the number of DNA bases in genes by adding a sequence
What is deletion mutation when it comes to genes
Changes the number of DNA bases in genes by taking away a sequence
What is duplication mutation when it comes to genes
Copies a sequence 1 or more times
What is gene flow when it comes to gene variations
Transfer of genetic variation from 1 population to another
What is genetic drift in reference to genetic variation
Change in frequency of existing allele in a population due to random sampling or organisms, this tends to reduce variation in population
What type of genetic variation is it when there is a change in a single base pair amino acid substitution
Missense variation
What type of genetic variation is it when there are changes in a base pair due to premature signals being sent to half constructed proteins
Nonsense variation
What kind of genetic variation is it when there are Changes in the number of DNA bases in genes by adding a sequence
Intertion variation
What kind of genetic variation is it when the number of DNA bases in genes change by taking away a sequence
Deletion variation
What kind of genetic variation is it when a sequence of DNA has be copied 1 or multiple times
Duplication variation
What is it called when one genetic variation moves from one population to the other
Gene flow
