Computer artwork of Mendels Second Law
Mendels Second Law. Computer artwork of Mendels Second Law, the genetic law of independent assort- ment. It was formulated by the Austrian botanist Gregor Johann Mendel (1822-1884), top left, after breeding garden peas (Pisum sp.). Round yellow seeded and wrinkled green seeded parents produce a first generation (F1) with round yellow seeds. Self-pollinating these produces a 9:3:3:1 ratio of round yellow, wrinkled yellow, round green and wrinkled green seeds (F2). Each parent has a pair of alleles for seed colour and another pair for shape, and in reproduction each randomly provides an allele from each pair. Alleles for yellow seeds and smooth seeds are dominant over the other two

EDITORS COMMENTS
This computer artwork showcases Mendel's Second Law, a groundbreaking genetic principle of independent assortment. The image depicts Gregor Johann Mendel, the esteemed Austrian botanist who formulated this law in the 19th century. Known for his pioneering work with garden peas (Pisum sp. ), Mendel meticulously bred round yellow seeded and wrinkled green seeded parents to observe their offspring. In the first generation (F1), he discovered that all seeds were round and yellow, indicating dominant traits inherited from both parents. Further self-pollination of these F1 plants led to an intriguing ratio in the second generation (F2): 9:3:3:1. This ratio unveiled a pattern where round yellow, wrinkled yellow, round green, and wrinkled green seeds appeared in predictable proportions. The explanation lies within each parent's pair of alleles for seed color and shape. During reproduction, these alleles are randomly provided by each parent to determine the characteristics of their offspring. Notably, alleles for yellow seeds and smooth seeds exhibit dominance over other variations. Mendel's Second Law revolutionized our understanding of heredity and laid the foundation for modern genetics. This remarkable artwork not only pays homage to Gregor Mendel but also celebrates his invaluable contributions to evolutionary biology and our comprehension of genetic inheritance patterns in diverse organisms like peas.
