|heredity ||The passing on of physical or mental characteristics genetically from one generation to another.|
|hybrid ||One allele is dominant and the other is recessive.|
|purebred ||Either completely dominant alleles or completely recessive alleles.|
|trait || a characteristic, typically one belonging to a person or animal or thing.|
|offspring ||the produced or child of the parents.|
|gene || a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.|
The Different forms of a gene.
An allele whose trait always shows up in the organism when the allele is present.
An allele that is masked when a dominant allele is present.
|homozygous ||Have two of the same kind alleles for a trait.|
|heterozygous ||Have two different kind of alleles for an trait.|
|genotype ||An organism’s genetic makeup,or allele combinations.|
|phenotype ||An organism’s physical appearance,or visible traits.|
|meiosis ||Is a process of cell division in which the number of chromosomes per c ell is cut in half creating haploid cells.|
|haploid || a cell that contains a single set of chromosomes.|
|diploid || containing two complete sets of chromosomes, one from each parent.|
|mutation ||A change in a gene or chromosome.|
|Insertation ||the action of inserting something.|
|Deletion ||the action or process of deleting something.
|Subsitution ||the action of replacing someone or something with another object or thing|
|sex linked genes ||
An gene that is carried on the XY Chromosomes.
A person who has one recessive allele for a trait however doesn't have the trait.
|sex chromosomes ||
A pair of chromosomes carrying genes that determine whether a person is a male or an female.
|genetic disorder ||An abnormal condition that a person inherits through genes and or chromosomes.|
A Chart that tracks which members of a family have or carry a particular trait.
|selective breeding || is the process by which humans breed other animals and plants for particular traits. Typically, strains that are selectively bred are domesticated, and the breeding is normally done by a professional breeder.|
A method of breeding in which two individuals with the identical or similar sets of alleles are crossed.
|hybridization ||An Method of breeding in which two genetically different individuals are crossed. |
An organism that is genetically identical to the organisms from which was produced.
|genetic engineering ||
The transfer of a gene from one organism’s DNA to the other.
|gene therapy ||the transplantation of normal genes into cells in place of missing or defective ones in order to correct genetic disorders.|
|mitosis ||Mitosis is the process in which a eukaryote cell seperates the chromosome in its cell nucleus into two identical sets of two daughter nuclei called diploid cells.|
|genetics ||the scientific study of heredity.|
|probabillity ||How likely something will occur. |
|punnet square ||A chart that shows all the possible combinations of possible alleles that can result from a genetic cross.|
|codominance ||neither two alleles are recessive or dominant.|
|messenger RNA ||RNA copies the coded message from DNA in the nucleus and carries to the cytoplasm.|
|transfer RNA ||RNA in the cytoplasm that carries an amino acid to the ribosome and adds it to a growing protein chain.|
|fertilization ||the joining of sperm and an egg|
|genome ||all of the DNA in one cell if an organism.|
