Heredity
Punnet Squares
Pedigrees
DNA structure and Function
Mutations
100
The passing of genetic material from parent to offspring.
What is Heredity?
100
A graphic used to predict the possible genotypes in an offspring.
What is a Punnet Square?
100
It traces the occurence of a trait through generations.
What is a Pedigree?
100
It was not discovered by one person but instead by many people
How was DNA discovered?
100
They are changes in the number,type,or order of bases on a strand of DNA.
What are mutations?
200
Gregor Mendel discovered that all the pea plants had characteristics and traits.
What did Gregor Mendel discover about Heredity?
200
It shows the probability of a certain event happening.
How do Punnet Squares make predictions about an offspring?
200
By organizing the information in a chart, a pedigree figures out when a certain trait was present.
How does a Pedigree trace traits through generations.
200
It is in the form of a twisted ladder or double helix.
What is the shape of DNA?
200
It is when a base is added to the code of DNA?
What is Insertion?
300
Both parents affect the offspring and their traits blend.
What is incomplete dominance?
300
It is a trait that will appear if at least one parent contributes it?
What is a dominant trait?
300
It is different because a pedigree traces the occurence of a trait through generations while a Punnet Square predicts the traits of an offspring.
How is a pedigree different from a Punnet Square?
300
It is made up of things called nucleotide. They join up to create it.
What is DNA made of?
300
It is the removal of a base in a code of DNA
What is deletion?
400
Both parents affect offspring and both traits are present.
What is codominance?
400
It is a trait that only appears if both parents contribute it.
What is a recessive trait?
400
It is needed to show that someone is recessive or dominant. This is done by checking if both parents have the recessive trait.
What is a Pedigree needed for?
400
They are made through a process known as replication.
How are copies of DNA made?
400
It is when one base is removed and another replaces it in a code of DNA
What is substitution?
