Linkage occurs between two genes when they are so near (less than 50 for Complete linkage and more than 50 but not more than 100 for Incomplete linkage) that they cannot undergo crossing over during meiosis and thus dont give new type of gametes which later could give recombinant(new type different than parents) character...

When is genetic drift likely to occur?
genetic drift may occur when a small group of individuals colonizes a new habitat
The tendency for the alleles on one chromosome to be inherited together is called?
genetic linkage?
Mutations and the genetic shuffling that occur during sexual reproduction are both sources of?
Mutations and genetic shuffling are two actions that occur during sexual reproductions. These scientific actions are both sources of genetic variation.
Genetic drift tends to occur in population that?
Are small
Genetic drift is most likely to occur in?
small populations
What is memory linkage?
what is a linkage linkage happens when a particular genetic loci or allele for genes are inherited jointly.
This occurs when specific alleles are inherited together?
Genetic linkage
What is a genetic map?
Genetic map is a graphic representation of a linkage group in the form of line which shows by points the sequence of the genes and the relative distances between the genes it contains. Genetic map is called a linkage map, or chromosome map.
X-linkage was discovered for the first time in?
Genetic linkage was first discovered by the British geneticists William Bateson and Reginald Punnett shortly after Mendel's laws were rediscovered. The understanding of genetic linkage was expanded by the work of Thomas Hunt Morgan. Morgan's observation that the amount of crossing over between linked genes differs led to the idea that crossover frequency might indicate the distance separating genes on the chromosome. Alfred Sturtevant, a student of Morgan's, first developed genetic maps, also known as linkage maps.
What has the author Jurg Ott written?
Jurg Ott has written: 'Analysis of human genetic linkage' -- subject(s): Linkage (Genetics), Human genetics
When is genetic drift likely to occur?

The tendency for the alleles on one chromosome to be inherited together is called?
genetic linkage?
Which research study focuses on the interaction between the environment and genetics in the development of psychological disorders?
Genetic linkage analysis
Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation
Linkage studies refer to tracing a particular trait within a family does this mean that twin and adoption studies are a type of linkage study?
No. Linkage studies use markers to identify chromosomal regions that may be linked to disease. Twin and adoption studies establish heritability and thus the genetic basis of a disease, not which chromosome or chromosomal region may be implicated. For this reason they are called genetic epidemiological studies.
Genetic drift tens to occur in populations that?
Genetic drift has a larger effect on smaller populations.
Mutations and the genetic shuffling that occur during sexual reproduction are both sources of?
Mutations and genetic shuffling are two actions that occur during sexual reproductions. These scientific actions are both sources of genetic variation.
