With reference to the description below, give the phenotypes and numbers of phenotypes in the progeny of the testcross?
Ebony body colour (e), rough eyes (ro), and brevis bristles (bv) are three recessive mutations that occur in fruit flies. The loci for these mutations have been mapped and are separated by the the following map distances. The interference between these genes is 0.4. A fly with ebony body, rough eyes, and brevis bristles is crossed with a fly that is homozygous for the wild type traits. The resulting F1 females are test crossed with males that have ebony body, rough eyes and brevis bristles; 1800 progeny are produced.
