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

Sexual reproduction produces offspring that are genetically _____________ to the parents.

Similar (but not identical)

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

When traits are blended together it is this type of inheritance patterns.

What is incomplete dominance

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
Asexual reproduction produces offspring that are genetically ____________ to the parent.
Identical
200
What is the punnet square used for?
To determine the outcome of genetic crossings.
200

When traits are dominant together at the same time it is this type of inheritance patterns.

What is codominance

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

Blood type inheritance is this type of inheritance pattern. (for example blood type AB is a good representation of this)

What is co dominance

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

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

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
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%

How many chromomsomes do humans have?
46 or 23 pair

The process through which reproductive cells are produced is called?

What is meiosis

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.
