Question

1. two heterozygous plants are crossed. what chance is there that the offspring will be white? what chance is there that the offspring will be purple?

probabilities
punnett square

Explanation:

Step1: Determine the genotypes of the parents

Since the plants are heterozygous, let's assume the allele for purple is \(F\) (dominant) and for white is \(f\) (recessive). The parents' genotypes are \(Ff\) and \(Ff\).

Step2: Create the Punnett square

	\(F\)	\(f\)
\(f\)	\(Ff\)	\(ff\)

Step3: Calculate the probabilities

• For genotypes: \(FF: 25\%\), \(Ff: 50\%\), \(ff: 25\%\)
• For phenotypes: Purple (\(FF\) or \(Ff\)): \(75\%\), White (\(ff\)): \(25\%\)

Answer:

• Genotypes (\%): \(FF: 25\), \(Ff: 50\), \(ff: 25\)
• Phenotypes (\%): Purple: \(75\), White: \(25\)
