To determine the probabilities of the offspring having purple or white flowers, I need a bit more detail about the genetic makeup represented in the Punnett square. Typically, in genetics related to flower color, purple is often represented by a dominant allele (P) and white by a recessive allele (p).
If the Punnett square you're referring to shows the mating of two heterozygous individuals (Pp x Pp), then the expected ratios are:
- 1 PP (homozygous dominant) - purple flowers
- 2 Pp (heterozygous) - purple flowers
- 1 pp (homozygous recessive) - white flowers
This would result in:
- 3 purple (PP and Pp) out of 4 total
- 1 white (pp) out of 4 total
This means the probability that the offspring will have purple flowers is 3 in 4, and the probability that the offspring will have white flowers is 1 in 4.
So, the correct answer would be:
purple: 3 in 4; white: 1 in 4.
