Mitochondrial DNA can be taken from bone, hair, or teeth and used in DNA typing. What are the benefits to using mitochondrial DNA over nuclear DNA? mtDNA requires a much smaller sample than nuclear DNA.

mtDNA is useful if the nuclear DNA is degraded.

mtDNA is inherited from the mother and father’s egg cells, unlike nuclear DNA.

mtDNA is present in all maternal relatives of the person being investigated.

because the light is a great source of energy for the plants to survive. (i hope this )

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).

what about it?

is this a ?
