If a heterozygous individual shows the complete effect of both alleles, the type of inheritance be?
Correct answer: D. Codominance
- A. Complete dominance
- B. Non dominance
- C. Incomplete dominance
- D. Codominance
Explanation
Complete dominance is a genetic phenomenon in which one version of a gene (the dominant allele) masks the effect of the other version (the recessive allele) when both are present in a heterozygous individual. Non-dominance, also called recessiveness, is a genetic phenomenon in which one version of a gene is not expressed in the phenotype when a dominant allele is present. Incomplete dominance is a genetic phenomenon in which the phenotype of a heterozygous individual is an intermediate blend of the two homozygous phenotypes. Codominance is a genetic phenomenon in which both alleles of a gene are expressed equally in the phenotype of a heterozygous individual.

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.
