When you see butterflies with different wing colors, you should conclude that there's a difference in their protein expression, so there's a mutation somewhere in the genome of the butterfly with the new color.
To answer the first question, if the desired color exists in nature, you should take the specific butterfly's caterpillars and raise them. If the desired <span>butterfly color doesn't exist in nature than you should wait for the mutation to occur (which could take many years) or look for the gene in the butterfly which is responsible for the pigmentation of their wings.

For the second question, mutations in the gene of the coloration of the butterfly's wing could change the color, so what scientist do is to try to provoke different mutations on the caterpillar's gene until they have a butterfly with the desired color.
So everything is about molecular genetics, every difference between species is due to mutations.
Answer:
Epistasis is a phenomenon in Genetics in which mutations on one gene locus are dependent on the mutations on some other genes locus. In other words, the expression of a phenotype of one gene is dependent on the presence or absence of mutations on other gene.
Dominance is phenomenon in genes in which a particular genotype masks the expression of alternative genotype and expresses itself due to complete takeover over other.
Answer: 1st law
Explanation: because the object will remain at rest (suck as the ball), which is modified by the action/ force
An animal cell that is placed in a hypotonic solution will rapidly gain water, because osmosis would cause the water to move to an area with more solutes. In this case, that is the inside of the cell. A cell in a hypotonic solution may gain enough water to lyse, or rupture, the cell membrane, which destroys the cell.
