Question

In fruit flies, the following X-linked traits are found: white eyes are recessive to red eyes, ebony body is recessive to gray body, and short wings is recessive to long wings.  A cross was made between wild-type males with red eyes, long wings, and gray bodies and females with white eyes, short wings, and ebony bodies.  Female heterozygote resulting from this cross, which had red eyes, long wings, and gray bodies, were then crossed with males with white eyes, short wings, and ebony bodies.  The F2 generation data is obtained below:

 

1299 white eyes, short wings, ebony bodies

1367 red eyes, long wings, gray bodies

99     white eyes, short wings, gray body

89     red eyes, long wings, ebony bodies

49     white eyes, long wings, ebony bodies

49    red eyes, short wings, gray bodies

1      red eyes, short wings, ebony bodies

1      white eyes, long wings, gray bodies

 

A) Calculate the map distance separating the three genes

B) Which gene is in the middle?
