Definition
FI = (1/2)^n x (1 + FA)
FA = inbreeding coefficient of ancestor |
|
|
Term
|
Definition
| location in the genome; a single nucleotide or a stretch of nucleotides |
|
|
Term
Single Nucleotide Polymorphisms
(SNPs) |
|
Definition
-Simpliest form of genetic variation
-Difference in the nucleotide present (A, G,T,C) at a single site |
|
|
Term
|
Definition
| short sequence motif, 2-6 BP long, repeated multiple times with different alleles having different numbers of repeats |
|
|
Term
|
Definition
| the occurrence in a population of several phenotypic forms associated with alleles of one gene or homologs of one chromosome |
|
|
Term
|
Definition
| in a population the less common allele occurs at a frequency of about 5 percent or greater |
|
|
Term
|
Definition
| occur less than 5 percent |
|
|
Term
|
Definition
| combination of alleles at multiple loci of the same chromosomal homolog |
|
|
Term
|
Definition
| sum total of all alleles in the breeding members of a population at a given time |
|
|
Term
| Hardy-Weinberg assumptions |
|
Definition
1. mating is random
2. all genotypes are viable
3. there are no subpopulations
4. only applies to large populations
5. All frequencies same in males and females
6. No migration
7. No mutation |
|
|
Term
| Positive Assortative Mating |
|
Definition
similar types mate;
tall mates with tall or short with short |
|
|
Term
|
Definition
|
|
Term
| 3 types of bias in mating |
|
Definition
1. positive and negative assortative
2. isolation by distance
3. inbreeding |
|
|
Term
|
Definition
-Ki square test only detect large deviations from H-W
-One or more assumptions could be violated and still not get significant deviations from H.W
-Agreement with H.W expectation is not proof that assumptions hold
-But significant deviation from H.W implies 1 or more assumptions violated. |
