According to Mendelian inheritance , a single character is controlled by one or more pairs of alleles. These alleles can either be dominant or recessive. Usually, dominant allele expresses itself by masking the expression of a recessive allele.

Question

Features of a Concept Features of a Concept Characteristics are discrete; that is, they are unitary. Genetic features have alternative forms, and each feature is inherited from one of the two parents. These are called alleles. One allele is dominant over the other allele. The dominant allele is reflected in the phenotype. Random segregation creates the gametes. The heterozygotic individuals produce gametes with an equal frequency of both alleles. Genes are unlinked; that is, different traits arise from the independent assortment.
