genetic information and vocabulary - class generated
| Term | Definition |
|---|---|
| allele | One variety of different forms of genes |
| dihybrid | Two different heterozygous traits |
| dominant | Over powers a recessive trait |
| F1 (first filial) generation | The offspring of the P parents |
| F2 (second filial) generation | The offspring of the offspring of the P parents |
| gene | Responsible for certain hereditary traits |
| genotype | A certain combination of a variety which includes different forms of genes of an organism |
| Gregor Mendel | He cross pollinated Pea plants and found out which one was dominant and which one was recessive |
| heterozygous | two different alleles paired together unless an incomplete dominence |
| homozygous | Having two identical alleles |
| hybrid | Another term for heterozygous |
| law of dominance | It dominates over the recessive form |
| law of independent assortment | Law stating that each gene from each alleles from the parents can be used for the alleles of the offspring |
| law of segregation | Law stating that they get one of the two genes from each parent |
| pedigree | Recorded traits of a family over multiple generations |
| phenotype | physical pheatures |
| Punnett square | Diagram used to predict gene outcome in an offspring |
| pure (purebred) | Another term for homozygous |
| recessive | Gene that can only be dominat when there is two recessive genes |
| allele | form of an altered gene |
| dihybrid | two different traits with dominate and recessive forms |
| dominant | trait most inherited from parental genes |
| F1 (first filial) generation | offspring from a cross of two vareies |
| F2 (second filial) generation | offspring from crosses amond individualsfrom F1 |
| gene | section of chromosomes that code for DNA proteien |
| genotype | gene pairs you get from parents |
| heterozygous | opposete gene from each parent |
| homozygous | same gene from each parent |
| hybrid | offspring from two different species |
| law of dominance | dominant from of traitdomimates or prevents expression of recessive form |
| law of independent assortment | defferent traits located on opposite homologous pairs of chromosomes sorted during gamete formation |
| law of segregation | gene pair responsible for trait separation so gamete recieves one gene for eac trait |
| pedigree | traits recorded over generations |
| phenotype | physical pheatures |
| Punnett square | chart used to determine genotypes of offspring in a cross |
| pure (purebred) | inherate same pheatures from each parent |
| recessive | least inherited trait from parental genes |
| allele | one of two or more different types of genes |
| dihybrid | a gene made up of 2 different traits |
| dominant | main characteristic in a gene |
| F1 (first filial) generation | first generation of genes in offspring |
| F2 (second filial) generation | crossing 2 members from the first filal generation |
| gene | transferred from parent to offspring to give them characteristics |
| genotype | total of genes transmitted from parent to offspring |
| Gregor Mendel | expiremented in breeding peas and is the founder of the science of genetics |
| heterozygous | a mixture of 2 or more things that don’t mix |
| homozygous | a mixture of 2 or more things that are the same |
| hybrid | a mixture of 2 different things |
| law of dominance | law stating that a factor in a pair of traits dominates the other unless theyre both recessive |
| law of independent assortment | genes for different traits located on different pairs of chromosomes |
| law of segregation | splitting of genes to give off only 1 gene to the offspring |
| pedigree | history of genes recorded from a long period of time |
| phenotype | a trait that is determined by the genotype |
| Punnett square | diagram used to predict the genes of the offspring |
| pure (purebred) | two of the same gene types |
| recessive | the trait that does not have dominance |
| allele | having 2 or more forms of genes |
| dihybrid | having 2 sets of separate traits |
| dominant | the trait that covers the recessive gene |
| F1 (first filial) generation | the result of having two separate parents |
| F2 (second filial) generation | the result of an F1 generation |
| gene | the specific instructions from the chromosome that determine your traits |
| genotype | the arangement of genes in organism that is determined by the alleles |
| Gregor Mendel | expanded on the laws of heredity; said that an offspring's genes don't necessarily come from its parents genes |
| heterozygous | when the genotype is different |
| homozygous | when the genotype is the same |
| hybrid | another word for heterozygous; an offspring from two different species |
| law of dominance | if you have two genes, and a capital letter is present, then the dominant gene will hide or overshadow the recessive gene. |
| law of independent assortment | states that genes separate by themselves during meiosis |
| law of segregation | states that genes separate in meiosis and each sex cell receives a gene pair |
| pedigree | a family's genetic traits over a period of time |
| phenotype | physical pheatures of an organism |
| Punnett square | the possibilty of genotypes in an offspring |
| pure (purebred) | an organism having two dominant traits |
| recessive | the less common trait of a species |
