Phylogeny + Diversity
This is the science of naming and classifying organisms
What is Taxonomy?
This is the observable trait of an organism.
What is a phenotype?
This is when humans choose which organisms reproduce based on desired traits.
What is artificial selection?
This is the definition of evolution in biology.
What is a change in allele frequencies over time?
This is the formation of new species.
What is speciation?
This is the total collection of genes in a population
What is a gene pool?
This is the genetic makeup of an organism.
What is a genotype?
These are organisms whose DNA has been directly modified in a lab.
What are GMOs?
This process explains how traits that improve survival become more common.
What is natural selection?
This occurs when populations are physically separated.
What is allopatric speciation?
This diagram shows how species are related through evolution.
What is a phylogenetic tree?
This law states that alleles separate during gamete formation.
What is the law of segregation?
This is one similarity between GMOs and artificial selection.
both aim to produce organisms with desired traits?
This type of selection favors one extreme of a trait.
What is directional selection?
This occurs without a physical barrier.
What is sympatric speciation?
This species concept groups organisms based on physical traits, but can be misleading when species look alike.
What is the morphological species concept?
This law states that genes for different traits are inherited independently.
What is the law of independent assortment?
This is one key difference between GMOs and artificial selection.
What is: GMOs directly modify DNA, while artificial selection uses breeding over generations?
This type of selection favors average traits and removes extremes.
What is stabilizing selection?
These are the three main steps of speciation.
What are barrier to gene flow, genetic divergence, and reproductive isolation?
This process occurs when a small group starts a new population, leading to reduced genetic diversity.
What is the founder effect?
This inheritance pattern shows both alleles fully expressed (like AB blood type).
What is codominance?
Name one concern about GMOs besides human health.
What is: reduced genetic diversity, corporate control, or herbicide-resistant weeds?
Name one type of evidence that supports evolution.
What are fossils, anatomy, embryology, or biogeography?
This type of isolation occurs when organisms breed at different times.
What is temporal isolation?
