In Drosophila melanogaster, black body (b) is recessive to gray body (B), purple eyes (pr) are recessive to red eyes (PR), and vestigial wings (vg) are recessive to normal wings (VG). The loci coding for these traits are linked, with the following map distances
The interference among these genes is 0.5. Pure line breeding cross Gray body, Red eye, normal wings with black body, purple eye, vestigial wings. If heterozygous female for all loci were allowed test cross, the of progeny with gray body, purple eye and vestigial wings out of 1400?

Early in the development of a plant, a mutation in cpDNA removes a specific BgIII restriction site (B) In this species cpDNA is inherited maternally. Seeds from the plant are grown, and the resulting progeny plants are sampled for cpDNA. The cpDNAs are cut with BgIII, and Southern blots are hybridized with the probe P shown. The autoradiograms show three patterns of hybridization:
Which of the following is correct about plant of seed?
a. plant of seed 1 having only mutated chloroplast
b- Plant of seed 2 having only normal chloroplast
c- Plant of seed 3 having only normal chloroplast
d- Plant of seed 3 having both normal and mutant chloroplast

A panel of cell lines was created from mouse–human somatic cell fusions. Each line was examined for the presence of human chromosomes and for the production of human haptoglobin (a protein). The following results were obtained: On the basis of these results, which human chromosome carries the gene for haptoglobin?
