Independent Assortment
Genotype and Phenotype

Genotype and phenotype information for F2 generation pea plants.

Regina Bailey

Genotype and Phenotype

In Mendel's experiment with pod color and seed color (Figure A) we see that the genotype or genetic makeup of the F1 plants is GgYy. The phenotypes or expressed physical traits are green pod color and yellow seed color. Both of these traits are dominant.

The F2 generation pea plants (Figure B) show two different phenotypes for each trait. Pod color is either green or yellow and seed color is either yellow or green. There are nine different genotypes that result from this type of experiment. The F2 generation genotypes and phenotypes can be seen in the image above.
