| 4157500107 | Chromosome theory of inheritance | Genes are located on chromosomes and that the behavior of chromosomes during meiosis accounts for Mendel's laws of segregation and independent assortment | 0 | |

| 4157559101 | Sex | An inherited phenotype character usually determined by which sex chromosome is present | 4 | |
| 4157565368 | Sex Linked Chromosomes | A gene located on either sex chromosome | 5 | |
| 4157566986 | X-linked genes | human X chromosome contains approximately 1,100 genes | 6 | |
| 4157581363 | The sex chromosomes carry ___________________ for some traits that are unrelated to sex characteristics | sex-linked genes | 7 | |
| 4157597112 | Recessive alleles causing color blindness are _____________ | X-linked | 8 | |

| 4157609452 | Linked genes | Genes that are genetically linked | 10 | |
| 4157613453 | Genetic recombination | Production of offspring with combinations of traits that differ from those found in either parent | 11 | |
| 4157622383 | Parental types | When one-half of the offspring are expected to inherit a phenotype that matches either of the parental phenotypes | 12 | |
| 4157638449 | Recombinant types, or recombinants | two nonparental phenotypes that are found among the offspring | 13 | |

| 4157655640 | map units | defining one map unit is equivalent to a 1% recombination frequency | 16 | |
| 4157659568 | Nondisjunction | The members of a pair of homologous chromosomes do not move apart properly during meiosis I or sister chromatids fail to separate during meiosis II | 17 | |
| 4157667053 | aneuploidy | An abnormal chromosome number | 18 | |
| 4157671158 | Monosomic | 2n-1 | 19 | |

| 4157680260 | Duplication | Repeats a segment |  | 22 |
| 4157685424 | Inversion | Reverses a segment within a chromosome |  | 23 |
| 4157688985 | Translocation | moves a segment from one chromosome to a nonhomologous chromosome |  | 24 |
| 4157697426 | ___________ can be reciprocal and nonreciprocal | Translocations | 25 | |
| 4157703955 | Down Syndrome | Due to trisomy of chromosome 21 | 26 | |
| 4157705432 | genomic imprinting | the phenotypic effects of a small number of particular genes depend on which allele is inherited from each parent | 27 |
