Answer:
The three genes in coupling are in repulsion.
Explanation:
Coupling happens when the dominant alleles and the recessive alleles are on the same homologous chromosome, while the repulsion happens when one chromosome has one dominant allele and one recessive allele and another homologous chromosome also has dominant and recessive alleles.
If the progeny has:
nb+ ls+ a/nb ls a ⇒ nb+ ls+ a
nb ls a+/nb ls a ⇒ nb ls a+
Where nb+ ls+ a is the dominant alleles and nb and nb+ is in middle.
ls+ nb+ are on the same chromosome (both dominant)
ls nb are on the same chromosome (both recessive)
ls nb, these two are in coupling with each other, but ls+ and a are on the chromosome and ls+ or nb+ are dominant, while nb+ and a are recessive on form a, thus, ls and nb, they are in repulsion with a.
 
        
                    
             
        
        
        
Answer:
The correct answer is option B. "Raoul's practice is massed; Scarlett's is distributed".
Explanation:
A massed practice condition is defined as a task that its performed by an individual without taking a significant amount of rest. Since Raoul is only taking 5 seconds of rest between trials, his practice is massed. On the other hand, distributed practice conditions involve resting for longer periods of time. Scarlett is resting 40 seconds between trials, which represents a longer period of time that the trial itself (30 seconds), therefore her practice is distributed.
