the heights of two true breeding strains of maize were both 1.75m and when crossed the F1 height was also 1.75m. Selfing the F1 produced an F2 with a range of heights from 1.59 to 1.91m. Out of the F2 of 451 plants there were 25 of the tallest. If the F1 was test-crossed, how many phenotypes would you observe?

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.
