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

epidermal cells are closely packed cells that secrete a waxy Cuticle that helps slow or prevent water loss.
Function of Cuticle:
Cuticle covers the leaves surface area and thus produce an obstruction in the transpiration activity (loss of water through leaves). In this way cuticle prevents or slow down the water loss.
The answer is 2.1 g/ml
D = M/V
105.5/50.0 = 2.1
