Question
- a trait for snapdragon flower is controlled by incomplete dominance. a red flower is crossed with a white. what percent will have pink flowers? 6. if two pink flowers are crossed, what percent of the offspring would have pink
Response
For the first question (red × white snapdragon, incomplete dominance):
Step1: Define alleles
Let \( R \) represent the allele for red, \( W \) for white. In incomplete dominance, \( RR \) is red, \( WW \) is white, \( RW \) is pink.
Step2: Determine parental genotypes
Red flower: \( RR \), White flower: \( WW \).
Step3: Perform cross (Punnett square)
| \( R \) | \( R \) | |
|---|---|---|
| \( W \) | \( RW \) | \( RW \) |
All offspring (\( RW \)) are pink. So 100% are pink.
For the second question (pink × pink snapdragon, incomplete dominance):
Step1: Parental genotypes
Pink flowers have genotype \( RW \) (since incomplete dominance, \( RW \) is pink).
Step2: Perform cross (Punnett square)
| \( R \) | \( W \) | |
|---|---|---|
| \( W \) | \( RW \) (pink) | \( WW \) (white) |
Step3: Calculate pink percentage
Offspring genotypes: \( RR \) (25%), \( RW \) (50%), \( WW \) (25%). So pink (\( RW \)) is 50%.
