Karyotype

Karyotype:
the number, size and shape (and bands) of the chromosomes of a somatic cell.

Overdominance

Overdominance:
the combined effect on a genetic trait of two alleles such that the heterozygote is more extreme than either homozygote. The effect of Aa is greater than AA or aa.
See also allele.

Pathogen

Pathogen:
an organism capable of inciting a disease.

Quantitative character

Quantitative character:
a character that is influenced by a group of genes at different loci, which are cummulative in their effect.
See also locus.

Strain

Strain: a group of individuals from a common origin.  Generally, a more narrowly defined group than a variety.

Trihybrid

Trihybrid:
resulting from a cross between parents that differ by three specified genes. Such as AABBDD x aabbdd => AaBbDd

Wild type

Wild type:
a strain, organism or gene of the type predominating in the wild population.

Xenia

Xenia:
the immediate effect of pollen on the character of the endosperm.

Hypothenemus hampei

Hypothenemus hampei: a small black beetle. The adult: females  1.4–1.8 mm long, males are smaller, 1.2–1.6 mm long. Female beetles can fly short distances; however males have no wing. CBB is the most destructive pest in the world.  See also Coffee Berry Borer.

Coffee Berry Borer

Coffee Berry Borer:
a small beetle bores the coffee fruit, lives then inside, and eats the coffee bean inside. 
Its scientificly name Hypothenemus hampei. CBB get also names Broca. In Indonesian language, CBB get name Penggerek Buah Kopi (PBKo).

Inbreeding:
breeding closely related organisms. 
In plants, by selfpollination, sib-pollination, or backcrossing.

Immune:
free from attack by a certain pathogen.

Heredity

Heredity:
the transmission of genetic characters from parents to progeny.
