| Question | Answer |
|---|---|
| dihybrid cross | a cross between individuals that have different alleles for the same gene |
| codominace | a condition on which both alleles for a gene are fully expressed |
| incomplete dominance | a trait in an individual is intermediate between the phenotype of the individual's two parents because the dominant allele is usable to express itself fully |
| complete dominance | a relationship in which one allele is completely dominant over another |
| phenotypic ratio | the ratio of phenotypes produced by a cross |
| genotypic ratio | the ratio of the genotypes that appear in offspring |
| punnett square | a graphic used to predict the results of genetic cross |
| monohybrid cross | a cross between individuals that involves one pair of contrasting traits |
| probability | the likelihood that a possible future event will occur in any given instance of the event |
| heterozygous | describes an individual that has 2 different alleles for a trait |
| homoaygous | describes an individual that has identical alleles for a trait on both homologous chromosomes |
| phenotype | an organisms appearance or other detectable characteristic that results from the organisms genotype and the enviroment |
| genotype | the entire genetic makeup of an organism; also the combination of genes from one or more specific traits |
| allele | one of the alternative forms that governs a characteristic such as hair color |
| molecular genetics | the study of the structure of nucleic acids and the function and regulation of genes |
| law of independent assortment | the law that states that genes separate independently of one another in meiosis |
| law of segregation | Mende's law that states that the pairs of homologous chromosomes separate in the meiosis so that only one chromosome from each pair is present in each gamete |
| recessive | describes a trait or an allele that is expressed only when two recessive allele for the same characteristic are inherited |
| dominant | describes the allele that is fully expressed when carried by only one pair of homologous chromosomes |
| f2 generation | second generation of offspring obtained from an experimental cross of two organisms |
| f1 generation | generation of offspring obtained from an experimental cross of two organisms |
| P generation | the first 2 individuals that mate in genetic cross |
| true breeding | describes organisms or genotypes that are homozygous for a specific trait and thus always produce offspring that have the same phenotype for that trait |
| cross pollination | a reproductive process in which pollen from one plant is transferred to the stigma of another plant |
| self pollination | the transferer of pollen grains from an anther to the same flower or to the stigma of another flower on the same plant |
| pollination | the transferrer of the pollen from the male reproductive structures to the tip of a female reproductive structure of a flower in agiosperms or to the ovule in gymnosperms |
| trait | a genetically determined characteristic |
| heredity | the passing of genetic traits from parents to offspring |
| genetics | the science of heredity and of the mechanisms by which traits are passed from parent to offspring |
