Ancient History
The potential answer for a scientific question.
What is a hypothesis
This type of chromatin structure is observed when cells enter into prophase I of meiosis.
What is heterochromatin
This is the smallest unit of evolution.
What is Population
When two populations within the same geographical area diverge into separate species.
What is Sympatric speciation
An ecological interspecific interaction that usually involves animals consuming other animals.
What is Predation
A term used to describe a diploid individual that possesses two different alleles of the same gene.
What is Heterozygote
These are pulled apart during anaphase I of meiosis.
What are Homologous chromosomes
A force of evolution that exerts random effects on the gene pool of a population.
What is genetic drift
This is a force of evolution that tends to prevent speciation.
What is gene flow
A form of symbiosis that benefits both interacting species.
What is mutualism
A mutation that creates a new stop codon.
What is a Nonsense mutation
This is the number of chromosomes in a human cell that has just completed anaphase I of meiosis.
What is 46 chromosomes
A loss of genetic diversity that usually results from a rapid decline in population size.
What is the Bottleneck effect
The process when two new species evolve from a single parent species.
What is cladogenesis
A form of coevolution that occurs between groups of species.
What is diffuse coevolution
A theory that proposes mitochondria were once free-living bacteria.
What is Endosymbiosis theory
This is a phase of meiosis where crossover can occur.
what is Prophase 1
This type of natural selection reduces variation in the expression of a quantitative trait.
What is stabilizing selection
Anything that blocks interbreeding between related species by a preventing conception.
What is Prezygotic barrier
A type of mimicry where multiple species imitate each other to their mutual benefit.
What is Müllerian mimicry
This molecule is the corepressor of the trp operon.
what is tryptophan
This is the name given to the diploid, multicellular state within the normal life cycle of plants.
What is sporophyte
A type of selection that usually involves males competing for access to fertile females.
what is intrasexual selection
A probable outcome when the fitness of hybrids produced by two sister species is relatively high.
What is fusion
A process that enabled two related ground finch species to avoid direct competition while living on the same island
What is character displacement
