The passing of genetic material from parents to offspring.
What is heredity?
An organism that has one dominant and one recessive allele.
What is heterozygous?
A graphic used to predict the possible genotypes of offspring in a given cross.
What is a punnet square?
The genetic material in cells that is contained in a molecule.
What is DNA?
Changes in the number, type, or order of bases on a piece of DNA.
What are mutations?
A feature that has different forms in population.
What is characteristic?
The combination of alleles that you inherited from your parents.
What is genotype?
The mathematical chance of a specific outcome in relation to the total number of possible outcomes.
What is probability?
A set of rules and symbols used to carry information.
What is a code?
When a base is left out.
What is a deletion?
Segments of DNA found in chromosomes that give instructions for producing a certain characteristic.
What are genes?
What your observable traits make up.
What is phenotype?
An expression that compares two quantities.
What is a ratio?
A twisted ladder shape of DNA.
What is a double helix?
When an extra base is added.
What is an insertion?
The different versions of a gene.
What are alleles?
Contributes to the phenotype if one or two copies are present in the genotype.
What is a dominant allele?
This is a ratio that compares a number to 100.
What is a percentage?
A base, a sugar, and a phosphate group make a building block of DNA.
What is a nucleotide?
When one base replaces another.
What is a substitution?
An organism with two dominant or two recessive alleles.
What is homozygous?
Contributes to the phenotype only when two copies of it are present.
What is a recessive allele?
Another tool used to study patterns of inheritance.
What is a pedigree?
When the cell is able to make copies of DNA molecules.
What is replication?
Results from mutations that harm the normal function of a cell.
What is a genetic disorder?
