Answer:
1/4 or 25%
Explanation:
Let us assume that the fruit color trait in the tomato is represented by R and r. The dominant color red would be represented by R while the recessive color yellow would r.
If a true-breeding red fruit tomato (RR) is crossed with a true-breeding yellow fruit tomato (rr), the F1 would be thus:
RR x rr
Rr Rr Rr Rr
Since R is dominant over r, all the F1 offspring would produce red fruits with the genotype Rr.
At F2:
Rr x Rr
RR Rr Rr rr
RR and Rr = red
rr = yellow
<em>Hence, the proportion of the F2 offspring expected to be yellow would be </em><em>1/4</em><em> or</em><em> 25%</em><em>.</em>
