Question

1. if two pink flowers are crossed, what percent of the offspring would have pink flowers? what percent of the offspring can be

Explanation:

To solve this, we assume incomplete dominance (common in flower color inheritance, e.g., snapdragons) where:

• Let \( R \) = allele for red, \( r \) = allele for white.
• Pink flowers have genotype \( Rr \) (since \( RR \) = red, \( rr \) = white, \( Rr \) = pink).

Step 1: Set up the Punnett square for \( Rr \times Rr \)

	\( R \)	\( r \)
\( r \)	\( Rr \)	\( rr \)

Step 2: Analyze the offspring genotypes

• \( RR \): red (1 out of 4)
• \( Rr \): pink (2 out of 4)
• \( rr \): white (1 out of 4)

Step 3: Calculate the percentage of pink offspring

Pink offspring = \( \frac{2}{4} = 0.5 \), or \( 50\% \).

Answer:

\( 50\% \)
