(29 cards)
What is Mendelian Inheritance?
Inheritance of a trait is determined by genes, passed onto descendants unchanged.
How does Diploidy Preserve Variation?
Shelters rare, recessive alleles from selection.
What is the Result of Outbreeding?
Variation and heterozygote genotypes.
What is the Result of Inbreeding?
Loss of variation and homozygote genotypes.
What are Clines?
Gradual variation that follows a geographic distribution.
What are Ecotypes?
Different groups of phenotype occupying different habitats.
What is Convergent Evolution?
Unrelated species come to resemble each other due to similar selection pressures.
What is Co-Evolution?
Evolutionary change where a feature of one species acts as a selection pressure for another species.
What is Batesian Mimicry?
Harmless imitates harmful.
What is Mullerian Mimicry?
Multiple harmful species resemble each other.
