Question

Cross a pea plant that has green round peas(GGRr) with a pea plant that has yellow wrinkled peas (ggrr).what is punnett square and determine the genotypes.

Answer 1

Answer:

When crossing a pea plant that has green round peas (GGRr) with a plant with yellow wrinkled peas (ggrr) the genotype of the offspring will be GgRr (50%) and Ggrr (50%).

Explanation:

In pea plants for the trait:

• Pea color: green is dominant and yellow is recessive.
• Pea shape: round is dominant and wrinkled is recessive.

Parents:

Green round peas GGRr

Yellow wrinkled peas ggrr

For the cross GGRr X ggrr the Punnett Square shows the possible genotypes in the offspring.

Alelles    GR GR     Gr Gr

gr           GgRr   GgRr   Ggrr     Ggrr

gr           GgRr   GgRr   Ggrr     Ggrr

gr           GgRr   GgRr   Ggrr     Ggrr

gr           GgRr   GgRr   Ggrr     Ggrr

The result of this cross shows the probable genotypes and phenotypes in the offspring of pea plants.

Genotypes :

GgRr 50%

Ggrr 50%

Phenotypes:

Plants with green and round peas 50%.

Plants with green and wrinkled peas 50%.
