Genetics - Coggle Diagram
Genetics
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.
-
Punnett Square - A diagram that is used to determine where your genotype comes from
Variant a.k.a Recessive/mutation - an individual must inherit two copies of the mutated allele in order for the feature to be present
-
-
The Bothead experiment shows that the genes that are passed down from each of the parent. When we started with the parent bots and went to the babybots you had to roll the dice to see which allele would be passed down. The difference in alleles shows the different feature a person has.
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.

-
Beneficial
A second example of a beneficial mutation is having resistance to HIV. This is beneficial because HIV interferes with your body's ability to fight off diseases. Without HIV your body can fight of diseases and infections normally.
An example of a beneficial mutation is lactose tolerance. Lactose tolerance allows you to consume dairy without having negative consequences.
A beneficial mutation is a mutation that can increase your chance of survival or give you an advantage at life
Neutral
A second example of a neutral mutation ios having an eleventh finger. Having an eleventh finger is a neutral mutation because it doesn't affect your chances of survival.
One example of a neutral mutation is hair loss. Hair loss is a neutral mutation because losing your hair doesn't affect your chances of survival.
-
Harmful
One example of a harmful mutation is color blindness. Color blindness gives you a disadvantage because you are unable to see the correct color.
A second example of a harmful mutation is epilepsy. Epilepsy is a mutation that moves neurons in your brain which causes seizures.
-
Encyclopedia analogy citing mutations - A genetic mutation is similar to an encyclopedia. When you insert a page into an encyclopedia it could be a beneficial mutation because you are learning new information. When you rip a page out of a encyclopedia you lose information, which could be considered a harmful mutation. A neutral mutation could be adding in a page of information you already know.
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.
-
Gene - A piece of your hereditary that is passed down from your parents to determine a characteristic
Your genetics are the building blocks of you appearance. All your genetics are inherited from your parents.
Chromosome - An x-shaped structure that holds most of our genetic information in the form of genes
Your genotype holds all of your genetic information which includes genes, proteins, and chromosomes.
Encyclopedia analogy - Your genetic information is exactly like an Encyclopedia because an encyclopedia is sectioned off by different titles to determine where to find a word and our genetic information is sectioned off by different parts to determine where each traut originates from
Communicate information about artificial selection / the ways humans have changed the inheritance of desired traits in organisms
Screencastify Example (Rheumatoid Arthritis) - In this example of RA I said that you would have to select a gene from a jellyfish to replicate tissue . To do this you would have to artificially select a gene using CRISPR.
An example from class (Glow in the Dark Rabbit) - In class we mentioned in the slideshow that there are rabbits being genetically modified with a pigment so that they were able to glow in the dark. This is being done by replacing a pigment gene with a different gene from a different animal.
Fancy Fish - The article showed that Atlantic Salmon are being genetically modified to grow year round to help humans catch and eat more fish. This is being artificially changed with genes from another fish.
Edpuzzle - The edpuzzle showed a strand of DNA being cut out because it was either incorrect or not wanted. It was being cut out by an artificial gene and also being replaced with an artificial gene.
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

Construct an argument based on evidence for how environmental and genetic factors influence the growth of organisms
Both environmental and genetic factors both impact the growth of an organism. The genetic factors are going to be the foundation of your phenotype whereas the environment builds off the foundation and creates a new appearances.
-
-
Genetics is a little more influential towards your traits than your environment. This is because once you are born you immediately will receive your genetics from your parents whereas the environment can take a long time to overtake your genetics.
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 occur over many generations.
