Biology

Curly wing (CY) shape and stubblebristles (SB) are both recessive lethalalleles (i.e. dominant in terms of wing shape/bristles phenotype,but recessive for lethality). What would be the result(F₁ phenotypic ratios) of a cross between two curlywinged, stubble bristle flies? To develop a hypothesis to predictthe phenotypic ratio for the F₁ generation consider thefollowing:
What are the genotypes of the parents? _
What phenotypic ratio would you predict for the offspring of across between two flies with curly wing shape?
and two flies with stubble bristle?____
Use a branch diagram to predict theoutcome of dihybrid cross between two curly winged, stubble bristleflies.
