Question

Two genetic loci controlling two different traits are linked. During the inheritance of these traits, the Mendelian laws that would be affected is/are

• A. Law of dominance, law of segregation and law of independent assortment.
• B. Law of segregation and law of independent assortment.
• C. Only law of independent assortment.
• D. Only law of segregation.

Answer 1

Answer: (C)

Only law of independent assortment.

Mendel's law of independent assortment states that allele pairs separate independently during gamete formation. The traits are transmitted to offspring independent of each other. However, this is only true for the alleles which are far away from each other. When two different traits are linked, they do not follow the low of independent assortment. The traits are always transmitted together to offsprings as they are linked.

Thus, the correct answer is option C.
