Because they create multiple alleles, mutations can cause D. variations in traits.

<h2>Gene mutations and evolution</h2>

The production of mutations in DNA molecules is known as mutagenesis. Changes in DNA sequence or chromosome rearrangement are just two examples of mutations that can occur in DNA. These mutations can happen on their own, as a result of mistakes made during DNA replication or mitosis. Natural selection requires genetic variety, which is produced by spontaneous mutations.

The process by which populations of organisms change over generations is known as evolution. These modifications are caused by genetic differences. Different features in an organism can be introduced by genetic differences that modify gene activity or protein function. If a characteristic is beneficial and helps an individual survive and reproduce, it is more likely to be handed down to the following generation (a process known as natural selection).

Answer:

the chorion, the allantoids, the amnion and the yolk sac.

Explanation:

The amniotic egg has four layers. All of these layers are enclosed by a shell

The chorion helps for gas exchange. It's the layer that covers the whole embryo

The allantoid is a sac that helps with gas exchange but also is the one that encloses the wastes of the embryo during the development into the egg, one analogy is with the garbage bag, where all the waste is lookup

The amnion is the layer that protects the embryo, is like a jacket that surrounds the embryo

The yolk sac is the one that has the nutrients that are necessary for the embryo throughout all the development. It is like a lunch box for the embryo
