Explanation:
When breeders notice a unique trait of interest and selectively breed to increase their population, there is tendency of also increasing the population of lethal genes. This happens via a situation known as inbreeding depression. There is a tendency to mate closely related individuals in a bid to increase the occurrence of a desired phenotype. However, in a situation where these animals have a recessive lethal gene, it may result in a double recessive thus becoming obvious in the population.

Answer:
Physical change means that only the form / shape of the substance is changed , not the chemical properties. So here, cutting of paper is a physical change since it's shape is changed but the chemical properties remain the same.
Chemical: Chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction to transform other chemical substances.
Nuclear: Nuclear energy comes from splitting atoms in a reactor to heat water into steam, turn a turbine and generate electricity.
Kinetic: Kinetic energy is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has kinetic energy.
