Question

Give one significant difference between the following:

Linkage and crossing over

Answer 1

Sr. No.	Linkage	Crossing Over
1.	Linkage is the phenomenon where genes located close to each other on the same chromosome tend to be inherited together during sexual reproduction.	Crossing over involves the exchange of genetic material between homologous chromosomes during meiosis.
2.	Linkage will increase if the two genes are placed close to each other on a chromosome.	The frequency of crossing over increases in genes when they are placed far from each other.
3.	More parental lines are produced by linkage.	More recombinants are produced by crossing over.
4.	It helps to maintain the parental traits in the offspring.	It leads to the variation in the parental traits.
