Heredity The passing of traits from parents to offspring
Hybrid An organism that has two different alleles for a trait
Purebred The offspring of many generations that have the same traits
Trait A characteristic that an organism can pass on to its offspring through its genes
Offspring The children of an organism.
Gene The set of information that controls trait
Alleles The different forms of genes
Recessive Allele An allele that is masked when a dominant allele is present
Homozygous Alleles Having two identical alleles for trait
Heterozygous Alleles Having two different alleles for trait
Genotype an organism's makeup,or allele combination
Phenotype An organism's physical appearance,or visible traits
Dominant Alleles An allele whose trait always shows up in the organism when the allele is present
Punnett Square A chart that shows all the possible combinations of alleles that can result from genetic cross.
Codominance Alleles are neither dominant nor recessive.AS a result both alleles are expressed in the offspring
Probaility A number that describes how likely it is that an event will occur.
Meiosis The process that occurs in the formation of sex cells by which the number of chromosomes is reduced by half.
Haploid Half a chromosome
Diploid two complete sets of chromosomes,one from each parent
Chromosome A doubled rod of condensed chromatin.
Pedigree A chart that tracks which members will have a particular trait
Genetic Disorder An abnormal condition that a person
Sex-Linked Genes A gene that is carried on the X or Y chromosome
Sex Chromosomes A pair of chromosomes carrying genes that determine whether a person is male or female
Inbreeding A selective breeding method in which two individuals with identical or similar sets of alleles are crossed
Hybridization A selective breeding method in which two genetically different individuals are crossed
Clone An organism that is genetically identical to the organism from which it was produced
Gene Therapy The insertion of working copies o fa gene into the cells of a person with a genetic disorder in an attempt to correct the disorder.
Selective Breeding The process of selecting a few organisms with desired traits to serve as parents of the next generation.
Carrier A person who has one recessive allele for a trait,but does not have the trait
Genetic Engineering The transfer of a gene from the DNA of one organism into another organism,in order to produce an organism with desired traits.
Substitution Is a type of mutation where a base pair is replaced by another base pair.
Deletion A mutation in which a part of a chromosome or a sequence of DNA is missing.
Insertion THe addition of one or more nucleotide base pairs into a DNA sequence.
Mutation A permanent change in the DNA sequence that makes up a gene
Genome All the DNA in one cell of an organism
Karyotype A picture of all the chromosomes in a cell
