Answer:
Gregor Mendel
Step-by-step explanation:
He used pea plants in the 1800s to explain the principles of inheritance. He used simple traits such as color and height to show the laws of independent assortment where trait from the parent peas are independently and randomly passed down to offspring. He also showed the law of segregation where genes occur in pairs (alleles) and where offspring inherited only one of the allele from each parent.
