Answer:
It is a hypothesis that explains the origin of evolutionary reversions.
Explanation:
A phylogenetic tree may indicate that genes required for forming anatomical structures such as wings are not completely lost and they are activated many times during the evolution.
Answer:
I would expect to see 3 bands after completing DNA gel electriphoresis and staining the gel.
Explanation:
The restriction enzyme Hind3 has two Recognization sites in the 400 base pair long DNA molecule.
As a result the restriction enzyme Hind3 with generate 2 cuts in the target 400 base pair long DNA molecule.
The number of 2 cuts in the target DNA molecule will generate 3 DNA fragments.From this point of view it can be stated that 3 bands will form after completing DNA electrophoresis and staining the gel.
D. Shows how water molecules attract to the glass tube.
Answer:
A dominant allele is denoted by a capital letter (A versus a).Since each parent provides one allele, the possible combinations are: AA, Aa, and aa. Offspring whose genotype is either AA or Aa will have the dominant trait expressed phenotypically, while aa individuals express the recessive trait.
