Evolution
This is the definition for a change in allele frequency over time in a population
What is Evolution?
The mechanisms that acts on the individual - survival and reproduction of the organisms that are genetically best fit for their environment are selected for.
What is the definition of Natural Selection?
This is one of the examples of adaptation for a squid
What is camouflage or ink?
What type of speciation occurs when a population splits into two separate species in the SAMe area.
What is Sympatric Speciation?
The ability of an organism to survive and reproduce in its environment relative to others in the population.
What is Fitness?
A theory (explanation) supported by evidence for how populations change over time
What is evolution?
The variety of dog and cat breeds that we have today are a product of _________ _____________.
What is Artificial Breeding (Selective Breeding)
This type of reproductive isolation prevents egg and sperm from uniting to form a zygote.
What is a pre-zygotic isolating mechanism?
Which type of selection favors intermediate traits?
What is Stabilizing Selection?
In this isolating mechanism, hybrids are either infertile, or too frail to survive.
What is a post-zygotic isolating mechanism?
A group of organisms that can produce viable, fertile offspring
What is a species?
Evolution by natural selection can only occur if these two factors are involved (VICDA model)
What is Genetic Variation and Inherited traits)?
Do organisms acquire traits during their lifetime and then pass them on to their offspring?
No
This type of selection favors individuals with one extreme trait over the other extreme.
What is Directional Selection?
Female blue footed boobies only respond to the courtship displays of their own species
What is behavioral isolation?
A horse and a donkey produce a healthy mule baby, yet they remain separate species. Why?
What is mule offspring are sterile?
The frequency of the B allele is 0.7, while b allele is 0.3. What will the allele frequencies be in 5 years if this population is not evolving.
What is B allele is 0.7, while b allele is 0.3.
A little child catches a fly and pulls its wings off. The fly actually lives a better life, but does not pass its lack of wings on to its offspring. Why?
What is an organisms do not pass on acquired traits to offspring?
What is the definition of a population
What is a group of the same species, living in the same area at the same time?
Two separate populations breed at different times of the year.
What is temporal isolation?
Natural selection acts on the _______, and ____________ evolve as a result over time.
What is individual :populations?
