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

Genotype

100

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
100

Incomplete dominance

When 2 traits "blend" together, forming a new phenotype (Red flower + White flower= Pink flower)

200
Who first studied heredity and the passage of traits from one generation to the next?
Gregor Mendel
200

A filled in square represents...

An affected male

200

What is the punnet square used for?

To determine the outcome of genetic crossings (probability of offspring to have certain traits)

200
Name two traits that could be inherited from a parent?
Examples: hair color, eye color, height, skin color, freckles, etc...
200

Co-Dominance 

When both traits shows. (Blue flower + Yellow flower = Blue and yellow flower)

300
What type of organism did Gregor Mendel use to first study heredity?
Pea Plants
300

A non-filled in circle represents...

An unaffected or "normal" female

300

A black chicken (Bb) is crossed with a white chicken (bb). What percentage of offspring will be black?

50%

300
Why does a Punnet Square use capital and lowercase letters?
Capital = Dominant Trait Lower Case = Recessive Trait
300

In incomplete dominance, a Blue Unicorn is homozygous dominant. A Yellow Unicorn is homozygous recessive. What would the genotype for a green Unicorn be? 

Heterozygous (Aa or Dd or Bb etc.) 

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

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%

400

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

Dominant

400

A Tall penguin is homozygous recessive and a Short penguin is homozygous dominant. A heterozygous penguin is Medium. What example of dominance is this? 

Incomplete Dominance (mix of tall and short is medium) 

500

What is an allele?

A variation of a trait 

500

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"

500

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

Ee

500
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.

A blue and red striped bird is created when a blue bird and a red bird have offspring. How is this possible? What type of dominance is this?

The trait is showing that they got 1 allele from each parent. This is co-dominance
