In a test cross involving two linked genes, the offspring consist mostly of
- A. parental combinations of characters
- B. equal numbers of all four combinations
- C. recombinant combinations only
- D. non viable zygotes
Explanation
Because linked genes usually travel together, parental combinations outnumber recombinants, and the size of the minority reveals how far apart the genes lie. Equal numbers of all types would instead indicate independent assortment.
