Genetics
Ch 10 Biology
| Term | Definition |
|---|---|
| Genetics | Scientific study of heredy |
| Fertilization | Process in sexual reproduction in which male and female reproductive cells join t independentlyo form a new cell |
| Trait | Specific characteristic for an individual |
| True Breeding(Pure) | Same homorozygous |
| Hybrid | Same as heteroygous |
| Segreation | Separation of alleles during gamete formation |
| Independent Assortment | One if Mendel's principles that states genes for different traits can segregate independently during the formation of gametes |
| Gametes | Sex cells |
| Homozygous | Having two identical alleles for particular gene |
| Heterozygous | Having two different alleles for a particular gene |
| Phenotype | Physical characteristics of and organism |
| Genotype | Genetic makeup of an organism |
| Dominate | The gene that shows up |
| Recissive | An allele whose phenotype can only be seen when there are two copies of it. |
| Allele | One of a number of different forms of a gene |
| Incomplete Dominance | Situation in which one allele is not completely dominant over another over another allele |
| Codominance | Situation in which the phenotype produced by both alleles are completely expressed |
| Punnett Square | Diagram that can be used to predict the phenotype and phenotype combinations of genetics cross |
| Multiple Allele Trait | A gene that has more than two alleles |
| Polygenic Trait | Trait controlled by two or more genes |
| Sex-linked Trait | Gene located on a sex chromosome |
| Carrier | You have the gene but you don't have the diease |
| Autosome | Chromosome that is not a sex chromosome; also called autosomal chromosome |
