Question

Question 11 1 pts The fictional pathway below shows two pigment synthesis pathways that together give rise to the ur of the fruit fly. The gene shown below the arrows (st scarlet, cn cinnabar, bw- brown and se sepia; NOTE that these are not the real steps to pigment biosynthesis, which is much more complex). The questions below relate to this image. What colour eyes would flies that are homozygous mutant for bw have (i.e. bw/bw)? Colourless Intermediate B-cn Colourless Intermediate B- Colourless Intermediate D Colourless Brown pigment orange pigment Precursor C bw se Normal red eye O white brown O orange impossible to predict

Explanation / Answer

for question number 11

correct answer is BROWN.

EXPLAINATION

since genes are usually suceptible to mutation, so these genes are no exceptions.

mutation in the other gene in homozygous condition bw/bw fails to produce drosopterin, the red pigment , leads to brown colour of the eye.

this strain is called brown mutant.
