Question

two yellow and round seeded-plants with the genotype yyrr.
1 based on these results, which statements fit your observations? select all that apply.
the yellow trait must be tied to the round seed trait
the green trait must be tied to the wrinkled seed trait
the yellow seed trait can pair with a wrinkled seed trait
a green seed trait can pair with a round seed trait
a yellow seed phenotype can pair with a green seed phenotype

Explanation:

1. Analyze the first statement: The yellow trait (Y) and round trait (R) are independent in a dihybrid cross (YyRr × YyRr), so they aren't "tied" (linked) as per Mendel's law of independent assortment. So this is false.
2. Analyze the second statement: Green (y) and wrinkled (r) traits are also independent; they don't have to be tied. So this is false.
3. Analyze the third statement: From the cross, genotypes like Rryy (round, yellow? Wait, no—wait, Y is yellow, y is green; R is round, r is wrinkled. Wait, looking at the seeds: there are yellow (Y -) and wrinkled (rr) seeds (e.g., Rryy? Wait, no, let's check the phenotypes. Wait, the seeds: some are yellow and wrinkled (e.g., the ones with "rr" and "Y -"). So yellow (Y -) can pair with wrinkled (rr). So this is true.
4. Analyze the fourth statement: Green (yy) can pair with round (R -). For example, Rryy? Wait, no—wait, the green seeds (yy) and round (R -) would be Rryy? Wait, looking at the seeds, there are green (yy) and round (R -) seeds (e.g., the green round ones? Wait, the second row has a green round? Wait, the second row: "Rryy" is yellow? No, wait, Y is dominant (yellow), y is recessive (green). R is dominant (round), r is recessive (wrinkled). So a genotype like Rryy would be round (R -) and green (yy)? Wait, no—Y is for seed color (yellow dominant), so Yy or YY is yellow, yy is green. Rr or RR is round, rr is wrinkled. So a plant with genotype Rryy would be round (Rr) and green (yy). Wait, but in the image, there are green round seeds? Wait, the second row: "Rryy" is yellow? No, maybe I misread. Wait, the first row: "rrYY" (wrinkled, yellow), "RrYY" (round, yellow). Second row: "RrYy" (round, yellow), "Rryy" (round, green? Wait, no—yy is green, so Rryy is round (Rr) and green (yy). So yes, green (yy) can pair with round (Rr). So this statement is true.
5. Analyze the fifth statement: Yellow (Y -) and green (yy) are phenotypes of the same trait (seed color), so an individual can't have both yellow and green seed phenotypes. So this is false.

So the correct statements are "The yellow seed trait can pair with a wrinkled seed trait" and "A green seed trait can pair with a round seed trait".

Answer:

• The yellow seed trait can pair with a wrinkled seed trait
• A green seed trait can pair with a round seed trait
