The number of genes involved in the inheritance of color pattern. Introduction: According to Mendelian inheritance , a single character is controlled by one or more pairs of alleles. These alleles can be either dominant or recessive. Usually, a dominant allele masks the expression of a recessive allele. If the alleles are identical, they are called homozygous and if they are non-identical, the alleles are said to be heterozygotes.

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.
