when an individual has inherited two alleles for a trait that are different
a tool used to show all the possible offspring combinations from two specific parents
a diagram tracing a trait through a family
this picture shows all of the chromosomes from an individual, sorted in pairs
the two alleles that a person has inherited for a trait; example: TT
the physical expression of a trait; this is determined by the genotype
genetic information for an individual; deoxyribonucleic acid
an unexpected change in a gene or chromosome
the study of how traits are passed on from parent to offspring
only one allele is needed for trait to be expressed
two alleles are needed for trait to be expressed
father of genetics; he was the first person to study how traits are inherited. He used pea plants as his subjects.
regions of DNA within each chromosome that control for traits
in a eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA
the passing of traits from parents to offspring
