Question 1

Kearns-Sayre syndrome (KSS) results in progressive loss of vision and hearing, as well as heart defects. What is the genetic basis for this disease?

Question 2

The genes for light eyes (lt; light) and straw bristles (stw; straw) are tightly linked on chromosome 2 in Drosophila melanogaster. The Malpighian tubes of lt larvae and adults are maternally affected in that Malpighian tubes of lt/lt organisms, whose mothers were lt+/lt and have more yellow pigment than those from lt/lt mothers. There is no maternal effect associated with the straw locus. Give the phenotypes of the offspring from the following crosses.
FemaleMale
Cross #1:lt stw/lt stwlt+stw+/lt stw
Cross #2:lt+ stw/lt stwlt stw+/lt stw
Cross #3:lt+ stw+/lt stwlt stw/lt stw
