Mendel conducted a number of crosses and studies but could never discover linkage. What could be the reason for this ?
(i) Some genes are linked but they are too far apart for crossing over to be distinguished from independent assortment.
(ii) Linked genes were never tested for the same time in same cross.
(iii) The seven genes were present on the 7 chromosomes.
(iv) The genes underwent mutations during subsequent crossings.
Correct statements are:
(i) Some genes are linked but they are too far apart for crossing over to be distinguished from independent assortment.
(ii) Linked genes were never tested for the same time in same cross.
(iii) The seven genes were present on the 7 chromosomes.
(iv) The genes underwent mutations during subsequent crossings.
Correct statements are:
- a)(i) and (ii)
- b)(ii) and (iii)
- c)(iii) and (iv)
- d)(iv) only
Correct answer is option 'A'. Can you explain this answer?

Mendel could not find out linkage because all of his experimental characters of pea were not linked. They, were present either far apart from each other ovn the same chromosome pr present on the separate chromosomes.

Explanation:
Mendel conducted a number of crosses and studies but could never discover linkage. The reason for this could be a combination of factors. Let's evaluate each option:
(i) Some genes are linked but they are too far apart for crossing over to be distinguished from independent assortment.
- This statement suggests that some genes are indeed linked, but their distance is too far for crossing over to occur.
- Crossing over is the exchange of genetic material between homologous chromosomes during meiosis. It is a key process that leads to genetic recombination and the shuffling of alleles.
- If the genes are far apart, the likelihood of crossing over occurring between them is reduced. Therefore, it becomes difficult to detect linkage through traditional Mendelian crosses.
(ii) Linked genes were never tested for at the same time in the same cross.
- This statement suggests that Mendel did not test for linkage between genes simultaneously in his crosses.
- Linkage refers to the tendency of genes located close together on a chromosome to be inherited together.
- To determine linkage, it is important to perform crosses that involve multiple genes at the same time. If Mendel did not do this, he would not have been able to observe the inheritance patterns that indicate linkage.
(iii) The seven genes were present on the seven chromosomes.
- This statement suggests that each of the seven genes Mendel studied was located on a separate chromosome.
- If the genes are on separate chromosomes, they would assort independently during meiosis and not exhibit linkage.
- Therefore, this statement does not explain why Mendel could not discover linkage.
(iv) The genes underwent mutations during subsequent crossings.
- This statement suggests that the genes Mendel was studying underwent mutations during subsequent crossings.
- Mutations can alter the inheritance patterns and outcomes of crosses, making it difficult to determine linkage.
- However, this statement does not directly explain why Mendel could not discover linkage.
Conclusion:
Based on the explanations above, the correct statements are (i) and (ii). Some genes were likely linked but too far apart for crossing over to be distinguished from independent assortment, and linked genes were not tested simultaneously in the same cross. These factors could have contributed to Mendel's inability to discover linkage.
