Which of the Following Statements Would Be True If the Linkage

Question

Which of the following statements would be true if the linkage between two traits were complete?
A)Only the parental combinations of phenotypes could appear in the progeny.
B)The rules of independent assortment would hold true.
C)Combinations of phenotypes different from those seen in the parents would be produced.
D)The exchange of genetic material between chromosomes would be frequent.

Accepted Answer

If the linkage between two traits were complete, it would mean that the two genes controlling those traits are located very close to each other on the same chromosome. This would result in the two traits being inherited together as a single unit, with no or very few recombination events occurring between them. As a result, only the parental combinations of phenotypes could appear in the progeny.
