Genetics - Coggle Diagram
Genetics
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.
Genes
the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions
-
-
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.
-
encyclopedia analogy
A comparison or correspondence between two things because of a third element that they are considered to share. An analogy is usually framed in order to describe or explain the nature of something

-
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.
punnet square
A Punnett square is a chart that allows you to determine the expected percentages of different genotypes in the offspring of two parents. A Punnett square allows the prediction of the percentages of phenotypes in the offspring of a cross from known genotypes.
-
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.
A sexual reproduction results in offsprings with identical genes and sexual reproduction with genetic variation. Compare and contrast advantages and disadvantages os asexual and sexual reproduction.

-
construct an argument based on evidence for how environmental and genetics factors influenced the growth of organism
Genetic factors are more influential because it is like the main piece. Genetics is more important than environment by how we get some of our genetic information from our parents.
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.
mutation
the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA
-
Make a model to describe the process of natural selection in which genetic variation of some traits in a population increases some individual of surviving and reproducing in a changing environment. Provide evidence that natural selection occurs over many generation
