What is a dominant trait?
The inheritance of traits that are passed from parent to child, that both the parent and the child are affected by the trait or disorder that is related to that gene.
100
What are three things a pedigree shows?
Determine genotypes, identify phenotypes, also predict how the trait will be passed down.
100
What is inheritance?
Something that is inherited either from a long time period after someone dies or genetically.
100
Why is DNA important?
DNA contains the instructions needed for an organism to develop, survive and reproduce
100
What is a protein?
A protein is a molecule made of amino acids
200
What is an example of a recessive trait?
Attached earlobes, Straight hairline, and left-handedness.
200
How accurate are punnet squares?
Phenotypes may be predicted a better-than-chance accuracy using a punnet square.
200
People who have recessive traits, like blue eyes or red hair, are always heterozygous. Is this statement true?
No, people who have recessive traits always have homozygous for that gene
200
When DNA is replicated in eukaryote what happens?
Each orgin of replication forms a bubble of duplication DNA on either side of the orgin of replication
200
How does your body make a protein?
Your body forms a protein by building blocks called amino acids
300
What is one example of recessive allele?
Cystic fibrosis,Smooth chin and blue eyes
300
What are the 4 types of pedigrees?
- Autosomal Dominant (AD)
- X-Linked Dominant (XD)
- Autosomal Recessive (AR)
- Y-Linked
300
What determines the inheritance pattern?
The phenotype of an individual is usually determined by his or her genotype
300
What is the structure of DNA?
Two linked strands that wind up around each other to resemble a twisted ladder or a shape known as double helix
300
How to code a protein?
Each protein is actually coded for a section of DNA called gene's
400
What is autosomal dominance?
a pattern of inheritance, of some genetic disorders
400
What are some things that Punnett squares Cannot predict why?
Height, and heredity of traits that are acquired by only one parent.
400
What is a dominant type of inheritance?
a way a genetic trait or condition can be passed down from parent to child
400
What is the structure of tRNA?
It is a folded structure that has three loops in the form of a three-leafed clover
400
How do you code for proteins to make a trait?
Usually Genes that code for a protein come in different versions and shapes called alleles
500
If two parents are both heterozygous and have a child, what is the probability that the child would be phenotypically short?
there is a 1-in-4 chance of having a child that is short, or 25%.

In butterflies, the gene for black wings (B) is dominant to the gene for blue wings (b). For which of the following parental genotypes would 100% of offspring be expected to be blue?
bb x bb

How does body coding work?
Your body looks for energetic imbalances in the body, and it corrects all of them energetically
