II and IV only
To put this answer as simply as possible, an organism's genotype can change due to either a random mutation in the DNA/chromosomes or the insertion of DNA from one organism into the DNA of another organism.
It's called a mutation.
one which changes the characteristics of an organism so it moves in a direction. Like if stin colour mutated so it was darker the mutation was directional to make skin colour darker not lighter.
gene mutation
mutation and random mateing maybe not sure apex sucks anal
It helps minimize the effect of a random mutation.

mutations, recombination, random pairing of gametes
It's called a mutation.
The mutation theory is basically stating that mutation is one of the major factors that cause evolution. The mutation has to be a beneficial mutation, meaning that it has to help the survival of the organism that got the mutation. The mutation causes knew genes and diversity which can spread quickly throughout a population and eventually change the frequency of alleles (causes mutation) Remember the mutation has to be beneficial to the survival of the organism.
Both mutation and adaptation involve changes in an organism's genetic makeup in response to changes in the environment. Mutations are random changes in DNA that can lead to variations in traits, while adaptation is the process by which organisms adjust to their environment over time to increase their chances of survival and reproduction. Both mutation and adaptation play crucial roles in evolution.

random changes or variation in a DNA sequence
random changes of variations in a dna sequence
gene mutation
Mutations are random changes in an organism's DNA that can lead to new traits. These new traits can impact an organism's ability to survive and reproduce in its environment, influencing its chances of passing on these traits to future generations. Over time, accumulated mutations contribute to genetic diversity, which is essential for evolution by natural selection to occur.
in gene pool, it comes from a random mutation
