In humans, chromosomes 1-22. Matching pairs of chromosomes.
carrier
A heterozygous individual who appears normal, but genotypically possesses a recessive gene for a potentially harmful gene.
codominant alleles
Equal expression causes the phenotypes of both homozygous parent organisms to be produced in the heterozygous offspring.
hybrid
Offspring produced when two varieties or closely related individuals are mated;often done to increase size or vigor.
inbreeding
Mating between closely related individuals to produce pure results;however it sometimes can have undesirable results.
incomplete dominance
the inheritance pattern in which the phenotype of the heterozygote is intermediate to the two homozygous parents. Neither allele is strong enough to mask the other, so they combine.
multiple alleles
Some organisms such as flowers or rabbits can come in many different colors.The genetic trait for color is said to have this.
pedigree
A family tree; A graphic representation showing patterns of inheritance in a family or breeding group.
polygenic inheritance
A trait such as skin color which is affected by the combination of several different genes.
sex chromosome
In humans, Chromosome pair 23.;XX or XY
sex-linked trait
An inherited characteristic, such as color blindness, controlled by genes located on chromosomes 23.
testcross
A breeding technique used to determine if an individual is homozygous dominant or heterozygous for a particular trait.
