Abiotic components of an ecosystem include temperature, light intensity, altitude, humidity, soil pH, and other nonliving factors of an area with which the community interacts.

What is happening during this phase of Mitosis (Anaphase I)?

If a sperm cell contains 8 chromosomes, it comes from an animal that has  _______ chromosomes. 

For natural selection to occur, there must be some preexisting genetic variation in a population. Natural selection does not create the variation. Instead, it impacts individuals differently based on their genotype.

What are abiotic components?

Genotype is the genetic makeup of an organism. 

For a population to be in Hardy-Weinberg equilibrium there are no changes in gene frequencies from one generation to the next. 

Mitosis is the type of cell division associated with  _______ and  _______

Alternate forms of the same gene are called 

Occasionally, chromosomes fail to separate during meiosis, leading to a condition in which the diploid number is not normal. This phenomenon is called nondisjunction.
