Question

in a group of tomato plants, some individuals have red fruit and others have yellow fruit. in this group, the gene for the fruit color trait has two alleles. the allele for yellow fruit (f) is recessive to the allele for red fruit (f). this punnett square shows a cross between two tomato plants.
what is the probability that a tomato plant produced by this cross will be homozygous recessive for the fruit color gene?
0%
25%
50%
75%
100%

Explanation:

Step1: Identify homozygous recessive genotype

The homozygous recessive genotype for fruit color is $ff$.

Step2: Count total and target genotypes

Total Punnett square outcomes: 4. Number of $ff$ genotypes: 0.

Step3: Calculate probability

Probability = $\frac{\text{Number of } ff \text{ genotypes}}{\text{Total genotypes}} = \frac{0}{4} = 0\%$

Answer:

0%
