Answer:
The Restriction Fragment Length Polymorphism (RFLP) and the Polymerase Chain Reaction (PCR) are techniques used in molecular biology to identify polymorphisms in DNA samples obtained from different species, organisms, varieties, strains, etc. In the case of RFLP, the DNA is digested with restriction enzymes, so the resulting fragments have different lengths, while in the PCR technique the DNA fragments are obtained by successive amplification cycles and they have the same length.
Human sperm and eggs contain 23 chromosomes. Human zygotes contain 46<span> chromosomes. The type of cell division that produces gametes with half the normal chromosome number is called meiosis. It is used to produce cells for repair and asexual reproduction.</span>

Answer: The viral nucleic acid is most likely Deoxyribonucleic acid (DNA)
Explanation:
Unlike ribonucleic acid (RNA) where uracil can be found, thymine alongside adenine, cytosine and guanine are only found in DNA.
Thus, the presence of 10% thymine in the newly discovered virus makes its analyzed nucleic acid to be deoxyribonucleic acid (DNA)
If two Bb guinea pigs cross, there are four possible outcomes:
- both pass the B: the son is BB
- one of the pass the B and the other pass the b: the son is Bb
- both pass the b: the son is bb
Since B (being black) is dominant, the son will be black in both BB and Bb cases. In order for a son to be brown, he must be a pure bb specimen.
So, if all of the offspring are black, it means that all four guinea pigs are either BB or Bb, which in turn means that at least one of the parents passed the B gene.
