| Chromosome Theory of Inheritance |
|
Definition
| Mendelian genes have specific loci (positions) along chromosomes, and it is the chromosomes that undergo segregation |
|
|
Term
|
Definition
| 2 alleles for each gene separate during gamete formation |

Term
| Law of Independent Assortment |
|
Definition
| alleles of genes on nonhomologous chromosomes assort independently during gamete formation |

Term
|
Definition

|
Definition
| an aberration in chromosome structure resulting from attachment of a chromosomal fragment to a nonhomologous chromosome |

Term
|
Definition
| an aberration in chromosome structure due to fusion with a fragment from a homologous chromosome, such that a portion of a chromosome is duplicated |
