Question

refer to the punnett square below to answer this question. if two of the offspring mated with each other, what proportion of the progeny would be expected to show the recessive phenotype?

1/4
all
none
1/2
3/4

Explanation:

Step1: Determine the genotype of the offspring

From the Punnett square, all offspring have the genotype \(Ff\).

Step2: Create a Punnett square for the cross of \(Ff\times Ff\)

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

Step3: Calculate the proportion of recessive phenotype (\(ff\))

There are 4 possible genotypes (\(FF, Ff, Ff, ff\)). The proportion of \(ff\) (recessive phenotype) is \(\frac{1}{4}\).

Answer:

\(\frac{1}{4}\) (Option \(1/4\))
