Summary Introduction

To determine: The type of progeny produced by crossing white-flowered parental variety and first-generation hybrid.

Introduction. Gregor Mendel was an Austrianmonk, who worked on a pea plant to observe the pattern of inheritance of certain characters from the parent plant to the offspring. He termed the genes as factors that were passing on from one generation to another. Based on this, he proposed three laws, which came to be known as Mendel’s law of genetics.

Explanation of Solution

The cross made between the true-breeding white flower (rr) and first-generation hybrid(Rr) will produce red and white flowers. When this plant is crossed with a dwarf parent the progeny produced is as follows:

GametesRr
r

Rr

(red flower)

rr

(white flower)

r

Rr

(red flower)

rr

(white flower)

The progeny produced from the cross will consist of 50% of white flowers and 50% red flowers.
