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

In the use of INCOMPLETE DOMINANCE we use capital letters to represent BOTH alleles because

Neither allele is dominant or recessive over the other 

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 is known as the "Father of Genetics"

Gregor Mendel

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

The most common form of CODOMINANCE we have studied is___________________

Blood type
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 letters represent the parent generation ___________, the first filial or first generation_______________, and the second filial or second generation__________________

P, F1, and F2

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

What are the letters we use to represent the base of the genotype for INCOMPLETE DOMINANCE and what bases do we use for CODOMINANCE

C's or CC and I's/II/i/ii

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
Inherited traits that children get from their parents come from-
Genes
400
The physical trait observed in an offspring is known as it's -
Phenotype
400

Cross two parents.  One of them is type AO blood and one of them is type AB blood.  Give the genotypes and phenotypes for each offspring and the percentages.

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
How many parents are involved in asexual reproduction?
One
500
What do we call the genetic make up of the individual, represented by a set of letters?
Genotype
500
How many chromomsomes do humans have?
46 or 23 pair

A red and a blue flower genetically crossed and somehow all of the offspring were blue.  If you were to cross a red (CRCR) and purple (CRCB) flower, what would be the offspring genotypes and probabilities?

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.
