What is genetics?
The study of heredity.

What is heredity?
The passage of genetic instructions (traits) from parent to offspring.
100

Type of inheritance that ends in one overpowering the other.

Dominant/Recessive

100
Some genes can be hidden or covered up by another. These are considered to be-
Recessive

Blood Type has 4 types, this is an example of

Multiple Alleles

200
Where are genes located?
In the chromosomes
200

Who first studied heredity and the passage of traits from one generation to the next?

Gregor Mendel

200

Type of inheritance that has a shared power over another

Codominance

200
What is the punnet square used for?
To determine the outcome of genetic crossings.
200

Name two traits that could be inherited from a parent?

Examples: hair color, eye color, height, skin color, freckles, etc...

300
What are the threadlike structures of DNA that carry genes called?
Chromosomes
300
What type of organism did Gregor Mendel use to first study heredity?
Pea Plants
300

Type of inheritance that has a "MIX" of the parents phenotype

Incomplete Dominance

A black chicken (BB) is crossed with a black chicken (BB). What percentage of offspring will be black?
100%
300
Why does a Punnet Square use capital and lowercase letters?
Capital = Dominant Trait Lower Case = Recessive Trait
400

If you have two dominant alleles you would be 

Homozygous Dominant BB

The physical trait observed in an offspring is known as it's -
Phenotype
400

Type of inheritance that can have anywhere from 3 to 26 alleles

Multiple Alleles

Having dimples is dominant (D). Not having dimples is recessive. (d) Both parents are heterozygous for the dominant trait. What percentage of the children will NOT have dimples?
25%

Genotype
500
How many chromomsomes do humans have?
46 or 23 pair

Sexlinked is passed by a trait being on the x or y chromosome, if a mutation is x-chromosome link, who is more affected. Female or Males?

Males

Long ears are dominant (E) in rabbits. If one parent is homozygous dominant for the long ear trait and the other homozygours reccessive (e), what is the only possible genotype of the offspring?
Ee

Two dark brown rabbits have four offspring. Three of the offspring are dark and one is white. What does this tell you about the parents' genes for fur color?
Dark brown is dominant and white fur is recessive. Both parents are heterozygous.
