Linkage is the_________.a)Physical association of two genes present on...
When two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.

Linkage is the_________.a)Physical association of two genes present on...
Linkage refers to the physical association of two or more genes present on the same chromosome. This means that these genes are located close to each other on the chromosome and are therefore likely to be inherited together. The closer the genes are located on the chromosome, the more tightly they are linked and the less likely they are to undergo crossing over during meiosis.
Physical association of two genes present on same chromosome
- Linkage refers to the physical association of two or more genes present on the same chromosome.
- These genes are located close to each other on the chromosome.
- They are likely to be inherited together.
- The closer the genes are located on the chromosome, the more tightly they are linked.
- They are less likely to undergo crossing over during meiosis.
Generation of non-parental gene combination
- Linkage can also affect the generation of non-parental gene combinations.
- When genes are tightly linked, they are less likely to undergo crossing over.
- This means that the offspring are more likely to inherit the same combination of alleles as one of their parents.
- If crossing over does occur, it may result in new combinations of alleles that were not present in either parent.
- These new combinations are referred to as non-parental gene combinations.
Generation of parental gene combination
- In contrast, when genes are not linked, they are more likely to undergo crossing over during meiosis.
- This can result in the generation of new combinations of alleles that were not present in either parent.
- However, it can also result in the generation of parental gene combinations, where the offspring inherit the same combination of alleles as one of their parents.
