Albinism
Fertilization is when...
chromosomes cross over
cells replicate
egg and sperm join together
gametes are formed
Why are Cheetahs in danger of going extinct?
Cheetahs have mutations in their sperm, do not reproduce often, and many cubs are killed by lions
No one likes cheetahs so people are letting them go extinct
Cheetahs are not fast enough and cannot escape predators
Cheetahs are all genetically identical making them vulnerable to disease
What is true about a population?
They cannot reproduce
They have identical genes
They are members of the same species
All organisms having DNA as their genetic material is evidence that
Natural selection occurred
All organisms descended from a common ancestor
Genetic resistance rarely occurs
Mutations don't exist
What does natural selection require?
Many generations, non-changing environment, no mutations
Bacteria, plant life, and mitochondria
Stabilizing environments, carrying capacity, and biodiversity
Over-reproduction, genetic diversity, competition, best traits get passed to the next generation
Which of these is a biotic factor?
Number and kinds of prey in an ecosystem
Average temperature
Concentration of oxygen
Type of soil
What type of relationship occurs between a flower and an insect?

Predation
Parasitism
Commensalism
Carrying capacity is...
The largest number of individuals that an environment can support
Animals moving out of an area
Animals moving into an area
Births-deaths
What is happening from 1901-1941?
Population has slow growth
Population has exponential growth
Decrease in population size
What is happening from 1950-1970?
Exponential Growth
Slow growth of population
Decline in population size
