Linkage and Recombination

Morgan’s Experiment

Thomas Hunt Morgan studied the fruit fly Drosophila melanogaster to understand how sexual reproduction created differences. For the following reasons, he preferred to work with fruit flies or Drosophila melanogaster:...

What is Linkage?

In his research with flies, Morgan discovered that two genes didn’t follow the law of division. The percentage of parental combination should be higher than the non-parental combination if the two genes are on the same chromosome. The term “linkage” refers to the actual physical joining of genes. The gene is said to be related if many features are found on the same chromosome....

What is Recombination?

The interchange of genetic materials between different species, also known as genetic recombination or genetic reshuffling, results in the production of offspring with combinations of traits that differ from those that originate in either parent. In eukaryotes, meiosis-induced genetic recombination can produce a new genetic data sequence that can be approved from the parents to the offspring. Recombination typically happens in nature....

Difference Between Linkage and Recombination

Characteristics Linkage Recombination Definition Recombination through crossing over occurs more frequently when the distance between two genes increases and the linkage between them decreases. The probability of recombination decreases as the distance between two sites grows smaller. Genes Linkage helps to keep certain genes together in the same chromosome. Process of recombination mixes genes between chromosomes. Occurrence When two genes are very close to one another, it occurs. When two genes are spread out sufficiently, it happens. Law It does not follow the law of independent assortment. It follows the law of independent assortment....

Conclusion

We have read about linkage and recombination and how they differ, as well as about the various kinds of linkage and recombination, Morgan’s example, and other topics. Eye color and sex are both governed by the same chromosome. As a result, some genes are passed down through chromosomes from parents to children. In his research with fruit flies, Morgan found that while there were over a thousand fruit flies with red eyes, there was only one male fly with white eyes. Linkage describes the actual physical connection between genes. There are two categories of linkage: incomplete linkage and complete linkage. Based on the existence or absence of the non-parental combination, this division is made....
