What do we call the genetic make up of the individual, represented by a set of letters?

Genotype

What is a pedigree?

It's a diagram that shows the occurrence and appearance of phenotypes of a particular gene from one generation to the next

100
Some genes can be hidden or covered up by another. These are considered to be-
Recessive
100
How are traits passed from parent to offspring?
Through genes during reproduction
200
Who first studied heredity and the passage of traits from one generation to the next?
Gregor Mendel

A filled in square represents...

An affected male

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...

What type of organism did Gregor Mendel use to first study heredity?
Pea Plants

A non-filled in circle represents...

An unaffected or "normal" female

A black chicken (BB) is crossed with a black chicken (BB). What percentage of offspring will be black?
100%

Why does a Punnet Square use capital and lowercase letters?
Capital = Dominant Trait Lower Case = Recessive Trait

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

How can you tell two people are married in a pedigree?

There is a horizontal line connecting them 

400
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%

For some traits, only one copy of a particular gene is needed to show a given trait. These genes are referred to as-

Dominant

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

If in a pedigree, the trait shown is a recessive trait, then the only way someone would be affected is if they had a genotype of...

Two lowercase letters, or homozygous recessive- "hh" or "rr"

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.
