100
The name for the physical representation which corresponds with the combination of alleles for a given trait.
What is phenotype?
100

The longest stage of the cell cycle.
What is interphase (90%)?
300
The term used to describe a characteristic of healthy cells, which dictates that cells must be attached to other cells in order to divide.

What are mitosis and cytokinesis (10%)?
400
The term used to describe a characteristic of healthy cells, which dictates that cells will not continue to grow if the surrounding tissue is of a certain density.
What is density-dependent inhibition?
400
The failure of a chromosome to separate during meiosis resulting in aneuploidy, or an abnormal number of chromosomes in the resulting cell.

The reason why cancer tends to be a disease of the older.
What is it takes multiple mutations to result in a cancerous cell;these mutations build up over a lifetime?
500
The explanation for why genes closer in proximity on a chromosome are more likely to be inherited together than genes far apart.
What is the closer two genes are on a chromosome, the more likely they transfer together during crossing over?
500
