Genotypes of parents: Tt (3) × Tt (Q) % of each genotype: 1. Genotypes of parents: Tt (3) × tt (9) % of each phenotype: % tall, % dwarf % of each genotype: 3. Genotypes of parents: TT (3) X Tt (2) % of each phenotype: % tall, % dwarf % of each genotype: % of each phenotype: % tall, % dwarf Incomplete Dominance uhot alleles exnress themselves in the offspring.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
