Allele

Divers offspring
different combinations of alleles from each parent
Uniform offspring
offspring are identical to the parent
DNA
located in the nucleus determines the genetic traits of an organism
Gene
A segment of DNA found on a chromosome determines the inheritance of a particular traits
Heredity

Genetics
the study of heredity and variation of inherited characteristic
sexual reproduction
genetic material is donated from two parents offspring differ from each parent and each other
