6. Mutation - Importance of Mutations Flashcards
1
Q
What is single gene mutation and why is it important?
A
The generation of new genes (alleles) and non-coding sequences generates variation for evolution
2
Q
What are changes in chromosome structure and why are they important?
A
Gene duplication provides additional copies of genes which can be important in evolution. Generation of new chromosome structure increases chance of speciation.
3
Q
What is polyploidy?
A
When cells contain more than two paired sets of chromosomes
4
Q
How is polyploidy caused?
A
By errors during the separation of chromosomes during cell division (non-disjunction)
