Question

1. is it possible for two purple flowers to produce a white flower? use the punnett square below to show a possible cross combination of parents and possible offspring. ff x ff probabilities punnett square genotypes % phenotypes %

Explanation:

Step1: Create Punnett square

	F	f
f	Ff	ff

Step2: Calculate genotypes percentage

Total combinations = 4.

• FF: 1 out of 4 → $\frac{1}{4}=25\%$
• Ff: 2 out of 4 → $\frac{2}{4} = 50\%$
• ff: 1 out of 4 → $\frac{1}{4}=25\%$

Step3: Determine phenotypes

Assume F (purple) is dominant over f (white).

• FF and Ff: purple (FF - 25%, Ff - 50%, total purple: $25\%+50\% = 75\%$)
• ff: white (25%)

Answer:

Genotypes %	Phenotypes %

Yes, it is possible for two purple flowers (Ff × Ff) to produce a white - flowered offspring (ff) with a 25% probability.
