Genetics
The basics of Genetics
| Question | Answer |
|---|---|
| Traits | Phiyical Characteristics |
| Heredity | The passing of traits from parents to offspring |
| Genetics | Scientific study of Heredity |
| Pruebred | One that always produces offspring with the same form of a trait as the parents (homozygous) |
| Genes | Factors that control traits (a portion of DNA) |
| Alleles | Different forms of a gene (one for short and for tall) |
| Dominate Alleles | one whoes trait always shows up in an Organism when the allele is [resent (upper case letter) |
| Recessive Allele | One whose trait is masked or covered up when the dominate allele is present(lower case) |
| Hybrid | An organism that has 2 different alleles for trait ; is hederozygous |
| Probibility | The Chance |
| Punnet Square | Chart that shows all the possible combinations of alleles that can result from a genetic cross |
| Phenotype | physical appearance or visible trait that you can see in the person |
| Genotype | organism's genetic makeup or allele combination this you can't see |
| Homoaygous | 2 identical, either dominate or recessive, alleles for a trait |
| Heterozygous | has 2 different alleles for a trait, an upper case letter and lower case (hybrid) |
| Codoninance | Alleles are neither dominate or recessive,as a result neither allele is masked (results would be a mixed fur) |
| Meiosis | Process where the nuumber of chromosomes is reduced by half in order to form sex cells |
| Mutation | change in chromosomes or gene |
| Multiple Alleles | or more forms of a code for a single trait (for example blood type |
| Sex Linked Genes | X and Y chromosomes |
| Karyotype | picture of all the chromosomes arranged in pairs |
| How many PAIRS of Chromosomes does the body have? | 23 |
| How many Chromosomes does the body have? | 46 |
| How many chromosomes does a sex cell have? | 23 individual |
| Diploid | 2 complete sets of the chromosomes in the human body |
| Haploid | Number of unpaired chromosomes in a sex cell |
| Cloning | Off spring completely identical to the parent |
| DNA | the Hereditary materials made up of chromosomes |
| Cell Division | Results in 2 identical daughter cells identical to the parent cells |
| Father of genetics | Gregor Mendel |
