Answer:
recombination frequency = 4.5% or 4.5mu
Explanation:
to calculate the frequency of recombination between these genes
we have,
recombination frequency = [ number of recombinnants/total number of offsprings) x 100
total offspring  = 88 + 103 + 6 + 3
total offspring =  200
Gl ra 88............................ parent
 gl Ra 103.........................parent
Gl Ra 6..................................... recombinant
 gl ra 3................................................ recombinant
recombination frequency = {6+3/88 + 103 + 6 + 3} x 100
recombination frequency = 9/200 x1oo
recombination frequency = 0.045 x 100
recombination frequency = 4.5% or 4.5mu
 
        
             
        
        
        
The option which is not a characteristic of chordates is chloroplasts in their cells.
Chordates do have a dorsal supporting rod (vertebrates are types of chordates - they have a spine), a dorsal hollow nerve cord (within the spine), and pharyngeal pouches. However, they do not have chloroplasts, because that is a characteristic of photoautothropic eukaryotes, which chordates certainly are not.
        
             
        
        
        
Answer:
The correct option is : cells containing empty plasmid vectors
Explanation:
The blue-white screen is a technique which involves the rapid identification of the recombinant bacteria in a vector-based molecular cloning experiment. In this method, a DNA ligated vector is inserted in a host cell which is viable for transformation and grown in presence of X-gal.    
The cells that are transformed with the vectors having the recombinant DNA produce the white colonies. Whereas, the cells transformed with empty vector i.e. the non-recombinant plasmids, produce the blue colonies. 
 
        
             
        
        
        
Their body goes into lactic acid fermentation which is inefficient and does not produce ATP for energy.
        
             
        
        
        
Answer:
They would Mix?
Explanation:
This is a really good question if they don't mix then i guess they'd have 50% chance of being blue and 50% chance of it being purple
