Mendelian Genetics

What did Mendel call the two kinds of traits exhibited by the pea plants (one coming from the father, one from the mother)?

• Genesis

• Elective traits

• Alleles

• Quadrants

What do we call the result of the genotype (for example, the color of the peas)?

• Visible traits
• Physiotrait
• Genotype 2
• Phenotype

• Purple
• Green
• GG
• gg
