Two fruit flies with normal wings are crossed. Among their offspring are 89 with normal wings and 35 with dumpy wings. a. What are genotypes of the parents?

b. Which trait is dominant? Which trait is recessive? Explain how you know.

a. What are the genotypes of the parents? Both parental flies are Nn, Heterozygous for the trait

b. Which trait is dominant? Normal wings, NN or Nn

   Which trait is recessive? Dumpy wings, nn

Explanation:    

Due to technical problems, you will find the complete answer and explanation in the attached files.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
