| Question | Answer |
|---|---|
| the field of biology devoted to understanding how characteristics are transmitted from parents to offspring | Genetics |
| Genetics was founded with the work of | Gregor Johann Mendel |
| the transmission of characteristics from parents to offspring | Heredity |
| occurs when pollen grains produced in the male reproductive parts of the flower (anthers) are transferred to the female reproductive part of the flower (stigma) | Pollination |
| occurs when pollen is transferred from the anthers of a flower to either the stigma of the same flower or a flower on the same plant | Self-pollination |
| involves flowers of 2 separate plants | Cross-pollination |
| denotes plants that are pure for a trait | strain |
| each parental generation | P1 generation |
| the first filial generation | F1 generation |
| the second filial generation | F2 generation |
| dominates the other factor of a specific characteristic | Dominant factor |
| the trait that did not appear in the F1 generation but reappeared in the F2 generation | Recessive factor |
| States that a pair of factors is segregated, or separated, during the formation of gametes. | Law of segregation |
| States that factors for different characteristics are distributed to gametes independently. | Law of independent assortment |
| the study of the structure and function of chromosomes and genes | Molecular genetics |
| each of several alternatives of a gene (Mendel's factors are now called alleles.) | Allele |
| The genetic makeup of an organism that consists of the alleles that the organism inherits from its parents | Genotype |
| The appearance of an organism as a result of its genotype | Phenotype |
| Both alleles of a pair are alike | Homozygous |
| The two alleles in the pair are different | Heterozygous |
| The likelihood that a specific event will occur | Probability |
| A cross between individuals that involves one pair of contrasting traits | Monohybrid Cross |
| Diagram used to predict the outcome of certain crosses and predicts the probability of inherited traits | Punnett Square |
| An individual of an unknown genotype is crossed with a homozygous recessive individual | Testcross |
| Occurs when two or more alleles influence the phenotype | Incomplete Dominance |
| Occurs when both alleles for a gene are expressed in a heterozygous offspring | Codominance |
| A cross between individuals that involves two pairs of contrasting traits | Dihybrid Cross |
| The transmission of characteristics from parents to offspring | Heredity |
| Mendel is known most for his experiments with what? | Garden Peas |
| Each characteristic in pea plants occurred in 2 contrasting ________________ | Traits |
| In the pea plant experiments, which trait is dominant: purple or white? | Purple |
| In the pea plant experiments, which trait is dominant: long or short stems | Long stems |
| When pollen grains from the male reproductive part of a flower, called the anthers, are transferred to the female reproductive part of the flower called the stigma | Pollination |
| Involved pollination between two separate plants | Cross-Pollination |
| A factor that has no observable efffect on an organism's appearance when it is paired with a trait controlled by a dominant factor | Recessive Factor |
| A pair of factors is separated during the formation of gametes | Law of Segregation |
| Factors for different characteristics are distributed to gametes independently | Law of indepedent assortment |
| The study of the structure and function of chromosomes and genes | Molecular genetics |
| A segment of DNA on a chromosome that controls a particular hereditary trait | Gene |
| Because chromosomes occur in pairs, genes also occur in _____________ | Pairs |
| Dominant alleles (trait factors) are represented by what type of letter? | Capital letter |
| Recessive alleles (trait factors) are respresented by what type of letter | Lowercase letter |
| How many alleles do the offspring receive from each parent during fertilization during meiosis? | One allele from each parent |
| The genetic makeup of an organism, represented with letters (Gg; GG; gg, etc) | Genotype |
| The aPpearance of an organism (a flower is green) | Phenotype |
| When both alleles of a pair are alike, the organism is said to be _________________ | Homozygous |
| When two alleles of an organism are different, the organism is said to be _______________ | Heterozygous |
| The likelihood that a specific event will occur is _____________________ | Probability |
| A cross between individuals that involves 1 pair of contrasting traits is called ______________ | Monohybrid cross |
| Used to predict the probability that certain traits will be inherited by the offspring | Punnett Square |
