Genetics Vocab

an organism that has inherited a recessive allele for a genetic trait or mutation but does not display that trait or show symptoms of the disease.

• carrier

• heredity

• phenotype

• purebred

a situation in which both alleles for a gene are expressed equally (both are seen at the same time)

• carrier

• codominance

• genotype

• incomplete dominance

the transfer of a gene from the DNA of one organism into another organism, in order to produce an organism with desired traits

• codominance

• mutation

• phenotype

• genetic engineering

an organism’s genetic makeup or allele combinations (Tt, TT, tt)

• genotype

• phenotype

• polygenic inheritance

• purebred
