Question

the table below summarizes mendels results for the f2 generation.

mendels results
plant height 787 tall 277 short
flower color 705 purple 224 white
pod color 428 green 152 yellow
pod shape 882 inflated 299 constricted
seed color 6,022 yellow x green
seed shape 5,474 smooth 1,850 wrinkled

what number should replace the letter x in the \seed color\ row?
18,066
3,011
207
2,001

Explanation:

Step1: Recall Mendelian ratio

In Mendelian genetics for a single - trait cross in the F2 generation, the ratio of dominant to recessive phenotypes is approximately 3:1.

Step2: Calculate the value of x

We know the number of yellow seeds is 6022. Since the ratio of yellow (dominant) to green (recessive) seeds should be about 3:1, we can set up the proportion $\frac{6022}{x}=\frac{3}{1}$. Solving for x gives $x = \frac{6022}{3}\approx2001$.

Answer:

2,001
