I would say that many of our heritable traits are <span>influenced by several genes and by the environnement.
It's, for the biggest part, because of the mutations. You have your heritables traits thanks to your mom and your dad. But a mutation caused by either several rays like ultraviolets or chemicals can changed your traits.
Hope this helps !

I think its because vaccines are just to help your body learn how to fight off the virus, it’s not to actually give you the virus. Hope this helped!

Answer:
directional selection, is a mode of negative natural selection in which an extreme phenotype is favored over other phenotypes, causing the allele frequency to shift over time in the direction of that phenotype.
The mode of evolution that is represented by this example is
called coevolution. Coevolution is the process in which two independent species
influence the evolution of each other. This process involves natural selection.
There is nothing working as a forcing agent. Since this orchid named bumblebee
orchid is totally dependent on a single species named bumblebee for its
pollination and this evolution process, so this process is called coevolution. Various
other organisms also follow this method of pollination to continue their cycle
of evolution.
