The peas in Mendel have two chromosomes with three genes on them. The genes influence pod color, size and flower color. Size genes make peas either large or small.
Peas can have either white or purple flowers.
In color genes, gray is dominant over yellow and green, yellow is dominant over green. Large size is dominant over small size, and purple flowers are dominant over white. So the rarest kind of pea in the game is a small, white flowered, green pea and the most common is the large, purple flowered, gray pea. The model of peas in Mendel consists of single chromosome diploid reproduction. Features are totally dominant and have complete penetrance.
