1. Alpha1-antitrypsin
This is a protease inhibitor (Pi). Low serum levels of this antienzyme predisposes patients to early onset of emphysema and chronic liver disease. Ten percent of the adult population has the heterozygote genotype MZ in which intermediate levels of alpha1-antitrypsin is present. The incidence of liver disease in MZ is only mildly higher than the general population. (Normal ranges by genotype: normal MM: more than 250mg/deciliter, heterozygous MZ: 50 - 250 mg/dL, homogygous ZZ: less than 50 mg/dL)

2. Ecophene
The variety of phenotype s (visible physical characteristics or behaviors), from a single genotype (a specific combinations of allele s in a gene ), that can be observed in a population within a particular habitat.

3. Environmental variance
Within a population, the measure of how much of the variation of a particular phenotype is due to environmental factors (as opposed to variations in genotype - see genetic variance ). An example might be the height of a human as determined by such factors as nutrition or infectious diseases during childhood.

4. F-1 generation
"Filial-One" generation. The first generation of offspring which results after mating or genetically crossing two types of parents with different genotype s or phenotype s. (The parents are known as the P generation.)

5. Genetic load
* The number of harmful gene s maintained in a population . * The amount by which the average fitness of the population is lowered due to the harboring of harmful genes (relative to the fitness it would have if an ideal genotype was common in the population).

6. Genospecies
* A line of homozygous self- fertilizing organisms which perpetuates by inbreeding or cloning . * All genotype s in a species .

7. Genotype (adj. genotypic)
The genetic constitution of an organism. Compare phenotype .

8. Genotype
The genetic (alleleic) makeup of an organism with regard to an observed trait.

9. Hardy-Weinberg equilibrium
In a population containing the genotype s of AA, aa, and Aa, the frequency of AA will be p2, the frequency of aa will be q2, and the frequency of Aa will be 2 pq at equilibrium, where p is the frequency of A and q is the frequency of a. By the Hardy-Weinberg law, a ramdonly-mating population will eventually reach these frequencies and be at this equilibrium as long as there are no selection pressures on the population.

10. Hardy-Weinberg law
This genetics law states that the frequency of a given genotype will reach equilibrium in a randomly mating population and will stay constant over many generations in the absence of selection pressures.
