Polygenic characteristics
Polygenic characteristics
Traits controlled by multiple genes
Main problem with observable characteristics
Main problem with observable characteristics
Differences may be environmental, not genetic
How DNA bases are identified in sequencing
How DNA bases are identified in sequencing
Each base tagged with different coloured fluorescent dye
Why recently diverged species have similar DNA
Why recently diverged species have similar DNA
Less time for mutations to accumulate
What mRNA sequence comparison measures
What mRNA sequence comparison measures
DNA diversity and genetic diversity between organisms
Amino acid similarity and evolutionary relationship
Amino acid similarity and evolutionary relationship
More similar sequences = more closely related species
First step in immunological protein comparison
First step in immunological protein comparison
Inject serum albumin from species A into species B
More precipitate in immunological tests indicates
More precipitate in immunological tests indicates
Greater protein similarity and closer evolutionary relationship
Why use multiple methods to establish relationships
Why use multiple methods to establish relationships
Provides stronger evidence than single technique alone
Most direct evidence of genetic relationships
Most direct evidence of genetic relationships
DNA sequencing
