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?

In rabbit, spotted pattern is dominant over solid colour and short hair over angora . A F1 spotted short hair was test cross to solid colour angora stock. The cross produced

Spotted angora               - 26                        

Solid coloured angora     144

Spotted short hair            157                      

Solid colour short hair       23

A wild plant with genes AABBCC was crossed with a triple recessive mutant aabbcc. The F1 male hybrid (AaBbCc) was then back crossed with the triple mutant and the phenotypes recorded are as follows

AabbCc (50), aaBbcc(50), AaBbCc (100), aabbcc (100), AaBbcc (350), aabbCc (350)
