In pea plants, yellow seeds are dominant over green seeds. Round peas are dominant over wrinkled peas. Cross two pea plants that are heyerozygous for both traits.
Both have YgRw. Use 4 by 4 Punnett square.

To determine the possible outcomes of crossing two pea plants that are heterozygous for both traits (yellow/green seed color and round/wrinkled peas), you can use a Punnett square.
First, identify the genotype of each parent plant for both traits:
Parent 1: Yellow (Yy) seeds and Round (Rr) peas
Parent 2: Yellow (Yy) seeds and Round (Rr) peas
To create the Punnett square, write the alleles of each parent along the top and left side of the square:
| Y y
--------------
R |
--------------
r |
--------------
Next, fill in the boxes by combining the corresponding alleles from each parent:
| Y y
--------------
R | RRYy RrYy
--------------
r | RrYy rrYy
--------------
Now, you can see the possible genotypes of the offspring in each box of the Punnett square. To determine the corresponding phenotypes, remember that yellow seeds are dominant over green seeds, and round peas are dominant over wrinkled peas.
The possible genotypes are RRYy, RrYy, RrYy, and rrYy. Let's determine the corresponding phenotypes for each genotype:
1. RRYy: yellow seeds (dominant) and round peas (dominant)
2. RrYY: yellow seeds (dominant) and round peas (dominant)
3. RrYy: yellow seeds (dominant) and round peas (dominant)
4. rrYy: yellow seeds (dominant) and wrinkled peas (recessive)
Therefore, the resulting phenotypes of the offspring from crossing two heterozygous pea plants would be yellow seeds and either round or wrinkled peas, depending on the specific genotype.
