Solution
The correct option is B Dominance
Each trait is governed by a pair of the alleles, the alternative forms of a gene. The presence of contrasting alleles of a gene in an individual is referred to as heterozygous condition. For example, a plant with genotype “Tt” is heterozygous for the gene of height. Since expression of one allele is masked by the presence of another allele in heterozygous genotype, The masked allele is called as recessive and fully expressed allele is called as a dominant allele. The only dominant trait is expressed by them irrespective of the presence of both dominant and recessive alleles. Thus, the correct answer is option B.
