Evolution Unit 1 exam review Part 2

True or false: there is a basic relationship between amount of evolutionary change (nucleotide differences) and time

• True

• False

branches should have the same amount of change from ancestral nodes to be useful for clocking

• relative rate test

• validation

• aligned bases

• hybridization

true or false: molecular clocks show exact times of divergence in all lineages

• true

• false

true or false: rapidly changing genes are best suited to resolve ancient (deep) nodes

• True

• False

genes evolving rapidly are best suited to resolve

• deep relationships (nodes)

• recent relationships (nodes)

A gene evolving slowly is best suited to resolve

• deep relationships (nodes)

• recent relationships (nodes)
