Recombination DNA
produced by combining DNA from different sources; a product of genetic engineering
Heredity
the transmission of traits from one generation to the next
genetic engineering
The direct manipulation of genes for practical purposes.
Genetics
The scientific study of heredity
sicle cell
a genitic disoder
gene therapy
a technique that places a gene into a cell to correct a hereditary disease or to improve the genome
Punnett Square
diagram showing the gene combinations that might result from a genetic cross
sex-linked gene
gene located on the X or Y chromosome
Hetrozygous
having two different alleles for a trait
Genetics disorders
inherited from parents
Recessive
trait of an organism that can be masked by the dominant form of a trait
incomplete dominance
A pattern of inheritance in which two alleles, inherited from the parents, are neither dominant nor recessive. The resulting offspring have a phenotype that is a blending of the parental traits.
diabetes
A condition in which the body is unable to produce enough insulin, the hormone required for the metabolism of sugar
dominant trait
A genetic trait is considered dominant if it is expressed in a person who has only one copy of the gene associated with the trait.
Probability
A number that describes how likely it is that an event will occur
Purebred
An organism that always produces offspring with the same form of a trait as the parent.
Hybrid
An organism that has two different alleles for a trait
Genotype
An organism's genetic makeup, or allele combinations.
Phenotype
An organism's physical appearance, or visible traits.
Allele
Different forms of a gene
Gregor Mendel
Father of genetics
Homozygous
Having two identical alleles for a particular gene
