Dihybrid Punnett square

Create a dihybrid Punnett square with Pea.

1. Once you have the parental genotypes, select the gametes using 1-3; 1-4; 2-3; 2-4 method. Then create the 16 genotypes possible; summarize with the ending ratio to the right of the 16 squares.

R=round,r-wrinkled, T=tall, t=short, Y= yellow peas, y= green peas, P=purple flowers, p=white flowers.

  • Make the following Punnett square. RrYY x rrYy 16 box square.What are the phenotypic and genotypic ratios of the offspring?

2. Extra Credit: Worth an extra 10 points!!! Make the following Punnett square. RrYYTT x
rrYytt 8*8 or 64 squares. Use a blank sheet as needed.

  • What is the phenotypic ratio of the offspring?

Your gametes: 1-3-5; 1-3-6; 1-4-5; 1-4-6; 2-3-5; 2-3-6; 2-4-5; 2-4-6
