| Question | Answer |
|---|---|
| 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 |
