If two opposite alleles come together, one finding morphological expression masking the other, the fact is described as law of _________ ?
Correct answer: B. Dominance
- A. Inheritance
- B. Dominance
- C. Limiting factor
- D. Segregation
Explanation
Mendel's law of dominance describes how, in a heterozygote, one allele can express its trait while masking the expression of the other allele. The masked allele is recessive, but the relationship being described is dominance. Students may choose segregation because it is another Mendelian law, but segregation concerns separation of allele pairs during gamete formation.

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.
