1Day 1 Chapter: Principles of Inheritance and Variation in One Shot | NEET 2024 | Seep Pahuja
Unacademy NEET・1 minute read
Linkage is an exception to the law of independent assortment. It occurs when two genes are located close together on the same chromosome and are inherited together more often than not.
Insights
- Linkage refers to the tendency of certain genes to be inherited together more frequently than predicted by independent assortment, challenging the notion that genes on different chromosomes assort independently during meiosis.
- Understanding linkage can provide insights into genetic inheritance patterns and help explain why certain traits are often inherited together, shedding light on the complexities of genetic transmission beyond simple Mendelian genetics.

Recent questions
What is the law of independent assortment?
The law of independent assortment states that alleles of different genes segregate independently of one another during the formation of gametes.
How does linkage differ from the law of independent assortment?
Linkage is an exception to the law of independent assortment, where genes located close together on the same chromosome tend to be inherited together.
Can genes located far apart on a chromosome exhibit linkage?
Genes located far apart on a chromosome are less likely to exhibit linkage due to the increased likelihood of crossing over events during meiosis.
What is the significance of understanding linkage in genetics?
Understanding linkage in genetics helps researchers map the location of genes on chromosomes and predict the likelihood of certain traits being inherited together.
How does linkage impact genetic diversity?
Linkage can impact genetic diversity by influencing the likelihood of certain combinations of alleles being inherited together, which can affect the variability of traits within a population.
