Mutation are two types somatic and germ cell mutation...as there is mutation in germ cell it will alter the normal behavior and produce variation !
random fertilization also causes variation as different setup of genes meets with another different...so chances of variation increases !
and third crossing over is in meiosis when chiasmata forms....so in this two homologous chromosome attach to each other and on separation ... some part exchange so leads to variation !

Answer:
or our bodies the conversion from food energy to ATP happens in mitochondria. If your mitochondria are not working properly then you are less able to convert food into ATP. For cells that require a lot of ATP, for example your muscles, this is a problem and they may become weaker and get tired faster.
Explanation:
Answer:
Inside most every cell in your body, you have the same 46 chromosomes, carrying the same genes. But not all the cells in your body are the same. Nerve cells, blood cells, cells lining your intestine, they all look different and they do different jobs
