Genetic
Develop and use a model to describe that structural changes to genes (mutations) may or may not result in changes to proteins, and if there are changes to proteins there may be harmful, beneficial, or neutral changes to traits.

Examples
-
Beneficial
-
Become healthier, more athletic
-
-
-
Develop and use a model to show that sexually reproducing organisms have two of each chromosome in their cell nuclei, and hence two variants (alleles) of each gene that can be the same or different from each other, with one random assortment of each chromosome passed down to offspring from both parents.
Genes
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. Every person has two copies of each gene, one inherited from each parent.
-
Proteins
Many genes n the genome code for proteins. These are molecules of amino acids liked together in a very specific sequence that produce a functional..
-
Chromosomes
a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
-
Communicate information about artificial selection/ the ways humans have changed the inheritance of desired traits in organisms.
-
-
-
Communicate through writing and in diagrams that chromosomes contain many distinct genes and that each gene holds the instructions for the production of specific proteins, which in turn affects the traits of an individual.
-
-
Construct an argument based on evidence for how asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation. Compare and contrast advantages and disadvantages of asexual and sexual reproduction.

Encyclopedia
Bert Vogelstein built upon the encyclopedia analogy. “Each of us has an encyclopedia in our cells, and each page of that encyclopedia represents one gene,” explains Dr. ... Each “chromosome” book has about 1,000 pages—one for each gene on that chromosome. Every page is filled with about 1500 letters
-
-
Alleles
one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
-
-
Phentotype
the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment
-
Use a model to describe the process of natural selection, in which genetic variations of some traits in a population increase some individuals likelihood of surviving and reproducing in a changing environment. Provide evidence that natural selection occurs over many generations.
