Natural selection involve natural causes while artificial selection is by human breeding or human intervention.
The process of domestication is called artificial selection. Like natural selection, artificial selection acts by allowing differential reproductive success to individuals with different genetically determined traits in order to increase the frequency of desirable traits in the population. Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene.
5. Let the allele be represented by the letter D (dominant) and d (recessive) - not sure if there was any other information about what the trait is
Your table has to look like this:
Homozygous dominant Genotype is DD Phenotype is Dominant trait
Heterozygous Genotype is Dd Phenotype is dominant trait
Homozygous recessive Genotype is dd Phenotype is recessive trait
6. Punnet square
Parents are True breeding black (BB) and True breeding white (bb)
B B
b Bb Bb
b Bb Bb
You can imagine the squares around that. So, all the offspring would be Bb (heterozygous) so all would phenotypically look black.
Answer:
People staying at home helps by making the disease die slowly by not being able to find a host.
Answer:
Prokayotes may be defined as the organisms that lacks the nucleus and the membrane bound cell organelle. Eukaryotes have the well defined nucleus and contains the membrane bound cell organelle.
The evolutionary advantage that has been noticed in the eukaryotic cells is the compartmentalization of the cell. The cell compartmentalization separates the cell organelle into the specialized functions. This division of labor increases the efficiency of the cell and regulates the evolution of the complex multi cellular organism.
Answer:
d
Explanation:
d is the only choice that converts products into reactants like the example in the problem
