The Study of Heredity

The passing of traits from one generation to the next

A specific characteristic that varies from one individual to another

Sequence of trait that codes for a protein in protein synthesis which codes for a specific trait

The entire "library" of genetic instructions in DNA that an organism inherits

Alternative form of a gene (one member of a pair) located at a specific position on a specific chromosome (a letter)

an allele that produces the same phenotype whether its paired allele is identical or different (capital letter)

an allele that produces its characteristic phenotype only when its paired allele is identical (lowercase letter)

the combination of alleles located on homologous chromosomes that determines a specific characteristic or trait (the allelic combination such as Bb)

the observable physical or biochemical characteristics of an organism, as determined by the genotype (the expressed trait such as brown eyes)

term used to refer to an organism that has two identical alleles for the same trait (ex. BB or bb)

term used to refer to an organism that has two different alleles for the same trait (ex. Bb)

specialized cell involved in sexual reproduction (sperm or egg)

a one-trait cross

a two-trait cross (ex. color & shape)
