Mitosis PMAT
When does Interphase take place?
Before Mitosis, for 90% of a cell‘s life.
What is the difference between a Dominant and a Recessive trait?
Dominant traits always show up, while Recessive traits are weaker and are usually hidden.
Mitosis is where cells ______ and make more _____.
Divide and make more cells.
What is a homozygous trait?
Where both genes/traits are either Dominant or Recessive.
DNA is really important because…
It has your genetic information
In the stage of Anaphase, what pulls the chromosomes apart?
Spindles from centrosomes.
What is the difference between Anaphase 1 and Anaphase 2?
In Anaphase 1 spindle fibers are pulling chromosomes away, but in Anaphase 2 they’re pulling chromatids.
Chill division helps us understand ______ and ______.
