Question

Mendel did not deal with

• A. Segregation
• B. Linkage
• C. Incomplete dominance
• D. Both linkage and incomplete dominance

Answer 1

The correct option is D Both linkage and incomplete dominance

• Linkage refers to the presence of two different genes on the same chromosome. Two genes that occur on the same chromosome are said to be linked, and those that occur very close together are tightly linked. The term linkage was coined by TH Morgan and it was discovered by William Bateson, Edith Rebecca Saunders, and Reginald Punnett.
• Incomplete dominance is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele. This results in a third phenotype in which the expressed physical trait is a combination of the phenotypes of both alleles. It was discovered by Carl Correns.
• Hence Mendel did not deal with linkage and incomplete dominance.
• So, the correct answer is 'Both linkage and incomplete dominance'.
