That the Red flowers are a dominant trait, and the white flowers would be recessive.
The Red Flowers are Homogenous Dominant
In a punnet square, The Genotype ratio for the red flowers would be 2:2
The phenotype would be 4:0
For the white flower
The Genotype would be 1:1
and the phenotype would be 1:0
The white flowers are Homogenous recessive
Answer: A specific chemical binding to nociceptors
Explanation:
Answer:
frequency of the blue (B) allele 
frequency of the red (R) allele 
The number of blue plants expected is 
The number of red plants expected is 
The anticipated number of violet plants is 
Calculated chi square value
Explanation:
Frequency of blue allele is
Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

Frequency of other allele

Chi Square test

Calculated chi square value
Answer:
Glucose
Explanation:
Water is an obvious one. Dissolved in the water are traces of urea. And there are concentrations of sodium. No glucose though.
