Mutations 01/29/17

http://evolution.berkeley.edu/evolibrary/article/mutations_04

Summary: This week in class we learned about mutations. There are many different types of mutations like insertion mutations or substitution mutations. A mutation is a change in the DNA that can affect how we look on the outside. FUN FACT: There are some mutations that can be carried on from parent to offspring.

SP6: Constructing explanations and designing solutions
This week in class I constructed an explanation by looking at a type of mutation and inserted it into an origin story for our superhero in class.

X and Y linked traits 01/12

Summary: This week in class we learned about X and Y linked traits. The X and Y genes are the sex genes that determine whether we are a boy or if we are a girl. X and Y linked traits are shown through subscript when reading them out. Usually males are more likely to get recessive traits rather than females because they only need one of the traits. FUN FACT: If a dad carries a trait on his Y gene then only his sons can get the trait.

SP2: Developing and using models
We developed models by finding the traits and where to put each of the traits that we found We used the models to figure out what the percentage would be that the off spring will have that certain trait. FUN FACT: These models are called punnet squares.

Trait chance 01/06/17

Summary: This week in class we learned about trait chances. The trait chance is determined by the genotype of the parents if there are two dominant traits the baby will not have a recessive trait. Some traits have a 0% chance of appearing if there are only the same genotype. FUN FACT: The thing that calculates trait probability is called a punnet square.

SP4: Analyzing and interpreting data
We analyzed data in class by looking at punnet squares and determining the probability of the trait. We interpreted data by converting the probability of the trait into percentages.
