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?3. When female e+e flies are crossed to male e+e files, what is the probability that the progeny will have the trident marking? Write your answer as a reduced fraction - e.g 1/164. 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 - e.g 1/165. How many of the resulting flies would have a dark trident marking? Write your answer as a reduced fraction - e.g 1/16

An allele is a variant form of a gene.

5. The following recessive traits are found in fruit flies: vermilion eyes are recessive to red eyes, miniature wings are recessive to long wings, and sable body is recessive to gray body. A cross was made between true breeding wild-type males with true breeding females for vermilion eyes, miniature wings and sable bodies. All of the F1 generation are heterozygous and had the wild-type phenotype. The females from this cross were then test-crossed to males with vermilion eyes, miniature wings, and sable bodies. The progeny was examined and the outcome is as follows: a) Phenotype Red eyes, Miniature wings, Sable body Vermilion eyes, Long wings, Sable body Vermilion eyes, Miniature wings, Sable body Red eyes, Long wings, Sable body Vermilion eyes, Miniature wings, Gray body Red eyes, Long wings, Gray body Red eyes, Miniature wings, Gray body Vermilion eyes, Long wings, Gray body Number of Progeny 18 112 308 66 59 321 102 15 Using proper nomenclature, calculate the map distance between the…
