When dominant and recessive alleles express itself together it is called:
Correct answer: A. Co-dominance
- A. Co-dominance
- B. Dominance
- C. Amphidominance
- D. Pseudo dominance
Explanation
Co-dominance is the correct term for the expression of both dominant and recessive alleles in a heterozygous individual, resulting in the simultaneous expression of both phenotypes. Dominance describes the situation where the dominant allele masks the expression of the recessive allele. "Amphidominance" and "pseudo-dominance" are not commonly used or recognized terms in classical genetics.

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.
