Gentics unit

Heredity The passing of traits from parents to offspring
Hybrid A organism that has two different alleles for a trait
Purebred The offspring that many generations that have the same traits
Trait A characteristic that an organism can pass through it's genes.
Offspring The product or result of something
Gene The set of information that controls a trait.
Alleles The different forms of a gene
Dominant Allele An allele whose trait always shows up in the organism when the allele is present
Recessive Allele An allele that is masked when a dominant allele is present
Homozygous Having two identical alleles for a trait
Heterozygous Having two different alleles for a trait
Genotype An organism's genetic makeup, or allele combinations
Phenotype An organism's physical appearance, or visible traits
Meiosis The process that occurs in the formation of sex cells by which the number of chromosomes is reduced by half
Haploid Produced during meiosis and reduces the number of chromosomes in the Dipoid cell by half
Diploid Having paired sets of chromosomes in a cell nucleus or a cell
Mutation A change in a gene or chromosomes
Insertion the addition of extra DNA or RNA into a section of genetic material
Deletion losing a section of nucleic acid molecule or chromosome
Substitution To replace one gene or trait with another one
Sex Linked Genes A gene that is carried on the x or y chromosome
Carrier A person who has the recessive allele for a trait but not the trait
Sex Chromosomes The chromosomes that determine a persons gender
Genetic Disorders An abnormal condition that a person inherits through genes or chromosomes
Pedigreee A family tree that tracks all the members that have a certain trait
Selective Breeding The process of selecting a few organisms with the desirable traits to serve as the parents of the next generations
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 with identical alleles as it's producer
Genetic Engineering The transfer of a gene from one organism to another's dna
Gene Therapy The insertion of working copies into cells of a person with a genetic disorder
