This is the process by which a single cell divides to produce two identical daughter cells.
Mitosis

What is the term for the physical expression of a trait, such as "tall" or "short."
Phenotype

In a pedigree, what shape represents a male?
Square

What is the phase of mitosis and meiosis where chromosomes line up in the middle of the cell?
Metaphase
400
What are the missing genotypes?
TT, Tt, Tt, tt
