| 119042062 | trait | variation of a particular inherited character | |
| 119042063 | genetics | study of heredity | |
| 119042064 | cross-fertilization | process by which sperm from one flower's pollen fertilizes the eggs in a flower of a different plant | |
| 119043093 | hybrid | offspring of two different true-breeding varieties | |
| 119043094 | monohybrid cross | mating of two organisms that differ in only one character | |
| 119043095 | allele | alternative form of a gene | |
| 119043096 | homozygous | having identical alleles for a gene | |
| 119043097 | heterozygous | having different alleles for a gene | |
| 119043098 | dominant | descriptive of an allele in a heterozygous individual that appears to be the only one affecting a trait | |
| 119043099 | recessive | descriptive of an allele in a heterozygous individual that does not appear to affect a trait | |
| 119043100 | Punnett square | diagram showing the probabilities of the possible outcomes of a genetic cross | |
| 119043101 | phenotype | observable traits of an organism | |
| 119043102 | genotype | genetic makeup or an organism; an organism's combination of alleles | |
| 119043103 | testcross | mating of an individual of unknown genotype but dominant phenotype with a homozygous recessive individual | |
| 119043104 | dihybrid cross | mating of two organisms that differ in two characters | |
| 119419529 | intermediate inheritance (incomplete dominance) | -inheritance in which heterozygotes have a phenotype intermediate between the phenotypes of the two homozygotes -dominant gene isn't completely dominant over the recessive gene (Red + White = pink) | |
| 119419530 | codominance | inheritance pattern in which a heterozygote expresses the distinct traits of both alleles (blood types LaLa, LaLo) | |
| 119419531 | polygenic inheritance | combined effect of two or more genes on a single character | |
| 119419532 | chromosome theory of inheritance | generalization that genes are located on chromosomes and that the behavior of chromosomes during meiosis and fertiliaztion accounts for inheritance patterns | |
| 119419533 | gene locus | specific location of a gene on a chromosome | |
| 119419534 | genetic linkage | tendency for alleles of genes on the same chromosome to be inherited together | |
| 119419535 | sex-linked gene | gene located on a sex chromosome | |
| 125479234 | true-breeding | offspring identical in appearance to itself generation after generation | |
| 125479235 | Mendel's principle of segregation | The two alleles for a character segregate (separate) during the formation of gametes (sex cells), so that each gamete carries only one allele for each character | |
| 125479236 | particulate hypothesis of inheritance | heritable factors retain their identity generation after generation |
