the passing of genetic traits from parent to offspring
the trait observed in the first generation when parents that have different traits are bred.
A trait that reappears in the second generation after disappearing in the first generation when parents with different traits are bred
one set of instructions for an inherited trait
one of the alternative forms of a gene that governs a characteristic, such as hair color
an organism's physical appearance, or other detectable characteristics; visible traits
the entire genetic makeup of an organism; also the combination of genes for one or more specific traits. Represented by capital and/or lower-case letters.
the likelihood that a possible future event will occur in any given instance of the event
chromosomes that have the same sequence of genes and the same structure
a process in cell division during which the number of chromosomes decreases to half the original number by two divisions of the nucleus, which results in the production of sex cells
One of the pair of chromosomes that determine the sex of an individual. 23 in humans
a diagram that shows the occurrence of a genetic trait in several generations of a family
a chart that shows all the possible combinations of alleles that can result from a genetic cross
having different genes on a pair of chromosomes
an organism that has two identical alleles for a trait
the human practice of breeding animals or plants that have certain desired traits
continued breeding of individuals with similar characteristics to maintain the desired characteristics of a line of organisms
crossing dissimilar individuals to bring together the best of both organisms
making a genetically identical copy of DNA or of an organism
a science of manipulating the genes of living things to instill some desirable trait not present in the original organism. An example is a tomato given a gene to delay its rotting.
a laboratory technique in which genetic markers are used to identify the source of a DNA sample
The insertion of working copies of a gene into the cells of a person with a genetic disorder in an attempt to correct the disorder
