What are chromosomes?
Threadlike molecules that carry hereditic information.
Who is Reginald Punnett
He developed the punnett square
What is mitosis
A type of cell division that occurs in the cell cycle and it becomes two genetically identical daughter cells.
What is prophase?
It is the first stage of cell division where the nucleus disappears.
Who was Gregor Mendel?
He was the founder of the modern science of genetics.
What are examples of inherited traits?
Eye color, hair color, blood type
What is a punnett square?
A square diagram of possible maternal and paternal alleles.
What are 5 phases?
This is the number of phases in mitosis.
What is metaphase?
This is where the chromosomes line up at the center of the cell.
What are pedigrees?
A genetic representation of a family tree.
What are phenotypes?
Physical characteristics of an organism.
What is an acquired trait
a non-inherited trait that developed from environmental factors.
What are the primary purposes of mitosis?
Cell renewal, asexual reproduction and growth.
What is anaphase?
This is the phase where the chromosomes move away from each other.
What are genes?
DNA replication of cells.
What are traits?
A characteristic that can pass on to its offspring through genes.
Inherited trait
A quality or characteristic transmitted genetically.
What is cytokinesis?
The end result is one cell with two identical nuclei.
What is interphase?
A resting phase where the cell prepares for prophase.
What is dominant?

What is a physical trait?
A trait you were not born with.
What are alleles?
one of two or more alternative forms of a gene that arrives by mutation and are found on the same place on a chromosome.
What is the cell cycle?
Interphase, mitosis and cytokinesis form this.
What is meiosis?
A type of cell division that resolves in four daughter cells each with half the number of chromosomes of the parent cell.
What is recessive?
An allele that causes a phenotype and seems to disappear
