Maintaining a consistent, regulated internal environment; all organ systems maintain a stable internal environment despite external changes.

Mendelian law with during the formation of gametes (eggs or sperm), the two alleles (hereditary units) responsible for a trait separate from each other.

4 daughter cells produced, each daughter cell has half the chromosomes of the parent 2 sets of cell division involved

To cross two different pea plants, Mendel used an artist’s brush.

(Mendel’s terminology)A cross between two parents that breed true for different versions of a single trait.

(Mendel’s terminology)Mating, or crossing, of two varieties.

DNA replication

Mendelian law where alleles for different traits are distributed to sex cells (& offspring) independently of one another.

final stage of both mitosis and meiosis as cell divides

Cell preparing to divide as genes double; preparation of next division

Mendelian law with a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation.

dormant phase

(checkpoint if replicated correctly)

grow and replicate

division of daughter cells

initial stage of both mitosis and meiosis, stated by chromatin into visible chromosomes

(checkpoint - chromosomes lined in middle correctly); pulled chromosome pairs

sister chromatids separate and move toward opposite poles of the cell

(Mendel’s terminology)When the plants self-pollinate, all their offspring are of the same variety.

the process in which part of the output of a system is returned to its input in order to regulate its further output.

feedback the output of a system acts to enhancethe changes to the input of the system

feedback occurs when the output of a system acts to opposechanges to the input of the system; Ex: A thermostat
