In a test cross involving two linked genes, the offspring consist mostly of
Correct answer: A. parental combinations of characters
- 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.

About Mendel's Laws of Inheritance
Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
