I. Overexpression of bicoid and manos in female fly result cause gaps in the segmentation pattern and may results in loss of unsegmented extremities of the organism.
II. Antennapedia is usually used to specify second thoracic segment of the fly. But mutation in antennapedia results in legs rather than antenna grow out of head.
III. Deletion of pair rule gene usually delete portions of alternate segments.
IV. Overexpression of class A genelacking Class B results tformation of Carp- carp-carp-carp.
V. Overexpression of class c gene in plant lacking E gene results in sepl-petal-petal-sepl.

Genetics: What is the expected phenotype of the following mutants, either inDrosophila melanogaster or in Arabidopsis thaliana? (i) Overexpression of both bicoid and nanos in a female fly. (ii) Overexpression of the homeotic gene, antennapedia, in a female fly lacking hunchback. (iii) Deletion of the pair-rule gene, even-skipped, in a male fly overexpressingnanos. (iv) Overexpression of the Class A gene, APETALA1, in a plant lacking the Class B gene, APETALA3. (v) Overexpression of the Class C gene, AGAMOUS, in a...
Drosophila melanogaster (the pumice fly, sometimes called a fruit fly) normally has gray bodies. When two normal-looking flies ( coded parent 1 and parent 2) were crossed, all 100 of their offspring have normal gray bodies. From among the 100 offspring, two mating pairs are picked at random. One pair is coded Male 1 and Female 1; the other pair is coded Male 2 and Female 2. The Male 1 -female 1 mating produced 74 offspring with gray bodies and...
