1. Balanced stock
A genetic strain of any of several lab organisms (like fruit flies) which can be maintained as heterozygous individuals without requiring constant artificial selection for the heterozygotes, due to a number of lethal recessive gene s with the result that the homozygous females are sterile (unable to produce offspring) and the males with the wrong recessive alleles are dead. (Male fruit flies are not homozygous or heterozygous because they only have one allele per particular genetic loci in question).

2. Codominance
A type of inheritance in which heterozygotes fully express both alleles .

3. Complete dominance
The type of inheritance in which both heterozygotes and dominant homozygotes have the same phenotype .

4. Dominance
The property of one of a pair of alleles that suppresses the expression of the other member of the pair in heterozygotes .

5. Dominant
Refers to an allele of a gene that is always expressed in heterozygotes .
