How many inherited traits in peas did G. Mendel study? In what conditions do dominant signs appear? What features of the genotype are associated with the manifestation of recessive traits?

Mendel studied 7 signs. A dominant trait suppresses the manifestation of a recessive, etc. determines the manifestation of the trait in both dominant homozygotes and heterozygotes. The recessive allele is able to ensure the manifestation of the trait it defines only if it is in a homozygous state.
