If all four phenotypic combinations (parental and recombinants) are produced in an equal ratio of 1:1:1:1 then there would be:

Correct answer: A. No linkage between genes

  • A. No linkage between genes
  • B. Partial linkage between genes
  • C. Complete linkage between genes
  • D. Tight linkage between genes

Explanation

Appearance of recombinants in equal proportions to their parents in next generation indicates that two genes are present further away from each other.

About Inheritance

Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
