Let us suppose that two plants are crossed (mated). One plant (female) is homozygous dominant and produces chlorophyll, and the other (male) is homozygous recessive and does not produce chlorophyll. These two plants are considered the parental, or P generation. What would be the possible genotypes and phenotypes of these two individuals? Fill in the table below with the parental generation's descriptional information. Table 6.1 Parental Generation P Generation

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.
