In which one of the following types of dominance, genotypic and phenotypic ratios are same in F1 generation?
Correct answer: C. Incomplete dominance
- A. Co-dominance
- B. Complete dominance
- C. Incomplete dominance
- D. Over dominance
Explanation
This is correct. In incomplete dominance, the heterozygous phenotype is an intermediate of both alleles (e.g., red × white flowers producing pink). In the F1 generation, all offspring have the same intermediate phenotype and same heterozygous genotype, making phenotypic and genotypic ratios the same.

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.
