Cell cycle and cancer
G1 Checkpoint
The phase where homologous chromosomes separate.
Anaphase I
The law stating alleles separate during gamete formation.
Law of segregation
When heterozygotes show an intermediate phenotype.
Incomplete dominance
Sister chromatids separate at this phase.
Anaphase

Cyclins
Exchange of genetic material between homologous chromosomes
Crossing over
An organism with two different alleles for a trait.
Heterozygous
When both alleles are fully expressed
Codominance
Chromosomes line up in the middle of the cell
Metaphase
