1. In the fruit fly, very dark febony) body color is determined by the recessive e allele. The e+ allele produces a normal, wild-type, honey colored body. In heterozygotes, a dark marking called a trident can be seen on the thorax of the body but otherwise the body is honey-colored. 2. What kind of inheritance would produce this trident marking? 3. When female ere flies are crossed to male ete files, what is the probability that the progeny will have the trident marking? Write your answer as a reduced fraction - eg 1/16 4. A second gene D. when homozygous recessive, can produce a white colored trident marking in those flies capable of making a trident marking. When two heterozygotes for these two genes are crossed, how many white trident flies are produced? Write your answer as a reduced fraction - eg 1/16 5. How many of the resulting flies would have a dark trident marking? Write your answer as a reduced fraction - e.g 1/16

Can i please get help with the answer and please show me the work with an explaintion so I can understand 

1. In the fruit fly, very dark (ebony) body color is determined by the recessive e allele. The e+ allele produces a normal, wild-type, honey colored body. In heterozygotes, a dark marking called a trident can be seen on the thorax of the body but otherwise the body is honey-colored.
2. What kind of inheritance would produce this trident marking?
