|
What is the linkage group |
It is a group of linked genes on a chromosome |
|
|
What does Locus mean |
Specific location along a chromosome or particular gene is found |
|
|
The frequency of crossing over between any two genes can be stated as a percent |
Crossover percentage = number of recombinations / total number of offspring x 100% |
|
|
What is the marker gene |
It is a gene that confers an easily identifiable phenotype and is used to trace the inheritance of other Genes that are difficult to identify. it must be located on the same chromosome and Ideally at a very small distance from the gene being followed |
|
|
Link to jeans do not segregate independently because |
They are situated on the same chromosome linked genes can undergo recombination due to crossing over |
|
|
Crossing over occurs more frequently between genes located relatively _______ apart then for those located relatively _________ together |
Far, close |
|
|
How can genetic linkage maps be created |
By sorting genes according to the percentage crossover values |
