Allele association.
Linkage disequilibrium- measure of correlation in allele frequencies between two loci.
Non-random association indicated linkage disequilibrium while random does not.

What is random dating?
Random dating is a form of dating in which a person dates more than one person that a time .
What are some random experiments to do at home?
some random experiments you can do at home are... floating egg levitating egg breeding bacteria and a lot more
When are two populations considered new and separate species?
A new species can occur when;1. Change in allele frequencies-genetic drift can result in loss of alleles in a population-one allele becomes the only variation, becomes "fixed"2. Gene flow due to migration-movement of alleles into or out of a population3. Non-random mating-individuals have preferred mates rather than random4. Mutations-a change in DNA can be beneficial, neutral, or harmful5. Natural Selection-best adapted, more likely to survive
What happens when Rare allele is in a small population?
The smaller the population the greater the frequency the allele will increase. When the Old Order Amish came to America in 1744 it was a husband and wife. One of them was a carrier for a recessive genetic mutation. As time went on and inbreeding occured because of the small population more and more children were born with the genetic disorder.
How do you minimize random error?
The only way to minimize random error is to repeat the experiment more times to get a better average. This means your result is accurate but not percise
What is linkage disequilibrium?
Linkage disequilibrium is the non-random association of alleles at two or more loci. It is broken down by recombination. Linkage equilibrium = independence between allele frequencies at two different SNPs Linkage disequilibrium = Association between alleles at different SNPs (SNPs are Single Nucleotide Polymorphism - Pronounced snips)
What is a heterozygous mixture?
It is a mixture having different alleles at one or more corresponding chromosomal loci.
What is multiple aleles?
Multiple alleles indicates that either the study is being conducted on alleles at more than one gene locus, that the characteristic being studied is controlled by several alleles at different loci or that there are two or more alleles at a single gene locus.
What is a heterozygous phenotype?
Having different alleles at one or more corresponding chromosomal loci. Like people who are resistant to sickle-cell anaemia.
What is the difference between a factor and an allele?
A locus is a particular location or a marker on a chromosome. It can be a gene but really only needs to be an identifiable location on the chromosome. Alleles differ in that they refer to a particular sequence of DNA at a given locus. The distinction from loci is that multiple alleles can exist for the same locus. http://www.informatics.jax.org/silverbook/glossary.shtml
What is homozyous?
Having different alleles at one or more corresponding chromosomal loci.
What is the name given to genes that have more than two alleles?
Polymorphic locus or polymorphic gene. Many geneticists use the term locus (plr. loci) for a gene (i.e. section of a chromosome)
What is the relationship between genes and alleles?
The gene loci are the sites where the alleles reside on the DNA strand. Alleles at the same gene locus on each chromosome pair will determine the phenotypic expression of that gene pair. Of course this explanation is incomplete when more complex interactions between alleles come into play
Which represents polygenic inheritance of traits?
Breeding of parents and f1 offspring do not follow simple Mendelian patterns. Some simple polygenic traits (two gene loci multiple alleles at one locus) may appear to follow mendelian patterns...such as base coat color in horses. Multiple other dilution alleles at various loci modify the base coat color. More complex interactions between a series of genes become even more complex and sometimes no offspring of 2 parents that have the desired characteristic are produced in the F1 generation.
What does genesis loci mean?
Perhaps you mean genius loci, the guardian deity of a place, or more loosely, a place's characteristic atmosphere
What is a trait controlled by three or more alleles have?
multiple alleles
When more than two different alleles control a trait?
The presence of more than two alleles that control a trait is called multiple allele. An example of this is the group gene of ABO blood that has three alleles.
