Describe the different body senses and how they function.
Anit [1.1K]

Our brain receives signals from each of these organs and interprets them to give us a sense of what's happening around us.

STALIN [3.7K]

Answer:

Wingless offspring

Explanation:

Complementation is the terminology used for finding difference in the mutation of same or different gene.  

Two groups with same complementation have failed to complement each other.  

Thus, two wingless flies will have the same genotype i.e “ww”

When two wingless flies are crossed following offspring are produced  

ww * ww  

ww, ww, ww, ww

All the offspring are wingless too
