Question

Linkage decreases the frequency of

• A. Hybrid
• B. Dominant allele
• C. Recessive allele
• D. both A and B

Answer 1

The correct option is A

Hybrid

The correct option is A

Explanation of the correct option:

1. The genes adjacent to one another on a chromosome are referred to as linked genes.
2. Genetic linkage refers to the likelihood of related genes being inherited jointly.
3. Genes near one another are more likely to be connected than those that are further apart—the greater the connection, the lower the recombination frequency, and vice versa.
4. As a result, linking reduces the frequency of the hybrid.

Explanation of the incorrect option:

Option B:

A dominant allele is a gene variant that causes a certain phenotype despite the presence of other alleles.

Option C:

A recessive allele is a type of genetic coding that does not create a phenotype when a dominant allele is present.

Final answer: Linkage decreases the frequency of Hybrid.
