Answer: This is due to the theory of independent assortment of gene.
This means that gene separate and assort with each other, independently. There a gene that is recessive in the parents may not be recessive in the offspring.
A recessive gene is the gene that makes up the physical appearance of the offspring. While a dominant gene is the gene that exist in the offspring, but is not among the gene that makes up the physical appearance of the offspring.
For the two pure stock parent plants, their have yellow and blue as the dominant gene, while green and white are the recessive gene.
That's is why the yellow and blue gene has a tendency of occurrence in future generations.
For their first progeny which appears to be all green, is because the green gene has sorted themselves independently to be recessive, while others become dominant.
For the second progeny, the recessive gene from the parent plants which was carried by the offspring as dominant gene, now became recessive in some plants.

Answer:
The Miller and Urey experiment is a well-known classic experiment in which hypothetical conditions of the early Earth's evolution were simulated to test the possibility of chemical evolution. In fact, this was an experimental test of the hypothesis previously expressed by Alexander Oparin and John Haldane that the conditions that existed on primitive Earth promoted chemical reactions that could lead to the synthesis of organic molecules from inorganic ones. It was held in 1953 by Stanley Miller and Harold Urey. The apparatus designed for the experiment included a mixture of gases corresponding to the notion of the composition of the atmosphere of the early Earth in the 1950s, and electric discharges passing through it (simulating lightning strikes on the ground). The Miller and Urey experiment is considered one of the most important experiments in the study of the origin of life on Earth.
