2. What is linkage? Linkage refers to the phenomenon where genes that are located close to each other on the same chromosome are inherited together. It doesn't obey the principle of independent assortment.

3. About linkage:- Linkage was first observed by -Thomas Hunt Morgan (1910) in Drosophila melanogaster. His findings led to the concept of linked genes.

4. Types of linkage:- 1.Complete linkage :- Genes are so close together on a chromosome that they are almost always inherited together.

5. 01 02 Genes are close, but not so close, allowing for some crossing over and recombination. 04 2.incomplite linkage:-

6. Gene location:- Genes are located on chromosomes at specific positions called locus. The closer two genes are on a chromosome,they are less likely to be separated during recombination.

7. Linkage group:- A linkage group is a set of genes located on the same chromosome that tend to be inherited together. The number of linkage groups equals the number of chromosome pairs.

Ut enim ad Adora Montminy Crossing over:- Crossing over is the exchange of genetic material between homologous chromosomes during meiosis. It leads to recombination and new combinations of linked genes.

9. Practical application Plant breeding:- Linkage analysis helps in plant breeding by allowing breeders to select for favorable gene Genetic research :- It is crucial in studying genetic disorders and traits in plants.
