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

In some goats, the presence of horns is produced by an autosomal gene that is dominant in males and recessive in females. A horned female is crossed with a hornless male. The F1 offspring are intercrossed to produce the F2. What proportion of the F2 offspring will have horns?
