“How each of the following produces phenotypic ratios other than those Mendel observed: incomplete dominance, codominance, pleiotropy, epistasis”. Concept introduction: Gregor Johann Mendel studied the inheritance pattern on pea plant. He gave the two term dominant or recessive. The dominant and recessive gene described the inheritance pattern. The dominant allele can be expressed either in homozygous or heterozygous condition while the recessive allele expressed only in homozygous condition (in absence of dominant allele).

Answer 1

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.
