The reason for the splitting of characters in individuals with dominant characters in F2 obtained from first-generation hybrids is their

These individuals cannot be genetically homogeneous, because in their genotype there are different alleles of the same gene. When the first generation of one individual is crossed, two dominant alleles are obtained, and the other dominant and recessive, so that they have a genetic heterogeneity
