Question

in a group of scarlet rosemallow plants, some individuals have red flowers and others have white flowers. in this group, the gene for the flower color trait has two alleles. the allele for white flowers (f) is recessive to the allele for red flowers (f). this punnett square shows a cross between two scarlet rosemallow plants. what is the probability that a scarlet rosemallow plant produced by this cross will have white flowers? options: \\(\frac{0}{4}\\), \\(\frac{1}{4}\\), \\(\frac{2}{4}\\), \\(\frac{3}{4}\\), \\(\frac{4}{4}\\)

Explanation:

Step1: Identify white flower genotype

White flowers require homozygous recessive genotype $ff$, as $f$ is recessive.

Step2: Count Punnett square outcomes

The Punnett square has 4 total genotypes: all $Ff$. No $ff$ genotypes are present.

Step3: Calculate probability

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

Answer:

$\frac{0}{4}$
