Answer:

Nucleus

Explanation:

Prokaryotes are the singled cell organisms that do not have a true nucleus which means like eukaryotes they lack a membrane-bound nucleus. So the genetic material of prokaryote are present in the cytoplasm of their cell.

Apart from the nucleus prokaryotes also lack membrane-bound organelle like mitochondria or chloroplast which are present in eukaryotes and helps in ATP formation for the cell. So prokaryotes use the plasma membrane of cell for production of ATP.

Therefore an organism can be classified as a prokaryote if it lacks a nucleus and other membrane-bound organelles.

9. In guinea pigs, rough coat is dominant (R) to smooth coat (r) and black coat (B) is dominant to white coat (b). A rough black

lisabon 2012 [21]

Answer:

the genotype of the parent guinea pigs are as follows:

RrBb (rough, black) and Rrbb (rough, white)

Explanation:

Since the phenotype of smooth coat is present in the offspring, the parent genotype cannot have RR alleles for their coat. Similarly, the rough, black parent cannot have BB alleles in its genotype because that will not yield a white coat color in its offspring.

After making the dihybdrid cross, the probability obtained for each phenotype is given below:

rough black: $\frac{3}{8}$

rough white: $\frac{3}{8}$

smooth black: $\frac{1}{8}$

smooth white: $\frac{1}{8}$

Hope that answers the question, have a great day!
