In the lab, a scarlet eye (st st bw+ bw+) and a brown eye (st+
st+ bw bw) fruit fly were crossed to form a heterozygous F1
generation containing a brick red eye phenotype (st+ st bw+ bw).
The F1 generation was self mated and the F2 generation had a
phenotypic ratio of 36 brick red to 14 brown to 8 scarlet to 1
white. If the eye color was an autosomal trait, the ratio would be
9:3:3:1, what would be the phenotypic ratio if eye color is a sex
linked trait? Why does the ratio not follow a Menedelian ratio?
