Term
|
Definition
| when the F1 yellow seed was self pollinated, it created a 3:1 ratio. when F1 yellow was crossed with a green, it produced a 1:1 ratio |

Term
| mendel's law of equal segregation |
|
Definition
| the two members (alleles) of a gene pair segregate from each other in meiosis; each gamete has an equal probablity of obtaining either member of the gene pair |
|
|
Term
|
Definition
| unlinked or distantly linked segregating gene pairs assort independently at meiosis |
|
|
Term
| ratios diagnostic of single-gene inheritance |
|
Definition
|
|
Term
|
Definition
| holds together two bivalent chromosomes; forms between the inner two chromatids |
|
|
Term
|
Definition
| used in fungi; chromatid ends up where it would if you draw out meiosis |
|
|
Term
|
Definition
| two copies of the dominant form of the allele |
|
|
Term
|
Definition
| one copy of the wild type allele is not enough |
|
|
Term
|
Definition
| the wild type copy is sufficient to produce the wild type phenotype |
|
|
Term
|
Definition
| each allele gives a certain degree of product that are both needed to exhibit the phenotype |
|
|
Term
| genes recessiveness occurs through |

Definition
|
|
Term
| genes dominance occurs through |

|
Term
|
Definition
| sequenes generated on a computer based upon sequencing traces |
|
|
Term
|
Definition
| rather than losing the organ all together, you converted them into some other part |
|
|
Term
| principles of inheritance can be applied in two directions |
|
Definition
| inferring genotypes from phnotypic ratios and predicting phenotypic ratios from parents of known genotype |
|
|
Term
|
Definition
| usually shows different phenotypic ratios in two sexes of progeny as well as different ratios in reciprocal crosses |
|
|
Term
| autosomal recessive disorders |
|
Definition
| equally males and females; appearance of the disorder in a progeny with unaffected parents |
|
|
Term
| autosomal dominant disorder |
|
Definition
| progeny are males and females; appears in every generation |
|
|
Term
| examples of autosomal dominant |
|
Definition
| polydactyly and picbald spotting |
|
|
Term
|
Definition
| two or more naturally occurring phenotypes; segregate as a single genetic locus with dominant or recessive alleles |
|
|
Term
|
Definition
| two morphs; most simple type of polymorphism; ex: tasters vs non-tasters |
|
|
Term
| x-linked recessive disorders |
|
Definition
| many more males than females show the phenotype; non of offspring ofm ales show the phenotype but daughters are carriers |
|
|
Term
| examples of x linked recessive disorders |
|
Definition
| red-green color blindness, hemophilia, duchenne muscular dystrophy, testicular feminization |
|
|
Term
| x-linked dominant disorders |
|
Definition
| affected males pass on the condition to all their daughters but none of their sons; |
