Answer:
Types of variation in genetics
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring)
other answer
There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA. Mutations themselves are not very common and are usually harmful to a population. Because of this, mutations are usually selected against through evolutionary processes
The apparatus is the instrument to perform various experiments in the lab. The apparatus is usually made up of glass.
These are the following apparatus used in the lab:-
Apparatus left for 15 minutes at each new light intensity before starting measurements to sterilize and make it pure and get the error-free readings.
Different light intensities are sensitive to the various bacteria and help to kill them.
