How many genes do pea plants have

WebFor instance, a recent study found over 400 genes linked to variation in height ^2 2. When there are large numbers of genes involved, it becomes hard to distinguish the effect of each individual gene, and even harder to see that gene variants (alleles) are inherited according to Mendelian rules.
