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.
-
-
Alleles - An allele is different type of gene, one member of a pair.
Phenotypes - Phenotypes are the physical representation of genotypes. An example of this is blue eye color or having curly hair.
-
Recessive Alleles - A type of allele that is more hidden. They will only appear as a phenotype if both genetics are recessive.
Bothead - An experiment where you roll a dice to figure out the genotype of the bot you were making, based on the probability and genotypes of the original bots. Then you would draw the phentoype out and if you got a mutation you would get a mutation card and draw that mutation in the phenotype.
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 segment of a part of DNA that gives instructions for a specific trait. You get 2 copies of each gene.
Protein
Assists the body in the strengthening of muscles and the bones in producing enzymes and hormones. Made of Amino Acids.
Chromosomes
A structure that carries genetic information. It is made of proteins and DNA put into the form of genes. A cell on average has 23 pairs of chromosomes.
Encyclopedia Analogy
The encyclopedia analogy is a row of books, you could say 23 books like the amount of chromosomes a human has. Each book contains information about certain topics, the pages are like the genes that a chromosome carries that code information for specific traits.
-
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.
-
Trait - A characteristic of an organism. Another way to call it is phenotype. Traits are determined by genotypes that come from your parents. An example would be the color of your eyes.
-
-
Communicate information about artificial selection / the ways humans have changed the inheritance of desired traits in organisms.
The "Fancy Fish" article was about changing a fish's DNA changing and modifying its genes to make it so it grew faster.
I did a screencastify on CIPA or the disease that causes you to not be able to feel pain. It is a genetic mutation and if used correctly it can help people who suffer from chronic pain, however this solution would likely only work on people who are hospitalized constantly because they must be monitored to make sure they are okay at all times.
The edpuzzle talked about how they can cure genetic diseases, make apples that do not brown, and make drought resistant crops.
We watched a video about CRISPR in class and this was the first time we learned about this technology. It explained how scientists take the genes from one organism and are able to put it into another.
Construct an argument based on evidence for how environmental and genetic factors influence the growth of organisms.
Genetics have more of an impact on traits than environment does because genetics are the very foundation of every one of your natural traits.
Many environmental factors either do not affect you or they don't affect your offspring, for example stress and PTSD.
The bodies foundation may be shaped up and changed a little bit by the environment, but it's still the genes that make up the majority of those traits because of the huge foundation.
Genes are the baseline of your entire body, and your genes tell you how to react to the environmental factors.
Construct an argument based on evidence for how asecual reproduction results in offspring with genetic variation. Compare and contrast advantages and disadvantages of asexual and sexual reproduction.
