What is genetics?
100
The passage of genetic instructions (traits) from parent to offspring.
What is heredity?
100
Sexual reproduction produces offspring that are genetically _____________ to the parents. Hint: Similar or different
Similar
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/reproduction
200
Genes are located here.
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. (Hint: identical or different)
Identical
200
This is used to determine the outcome of genetic crossings.
Punnett Square

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

What are the threadlike structures of DNA that carry genes called?
Chromosomes

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

If you are studying a population of genetically identical individuals, you can conclude that these individuals reproduce how?
Asexually

In a Punnet Square the lower case letter represents this.
Lower Case = Recessive Trait

Inherited traits that children get from their parents come from the parents ________.
Genes
400
The physical trait observed in an offspring is known as it's - (Ex. curly hair or straight hair)
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- (Hint: Recessive or Dominant)
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 parents are involved in asexual reproduction?
One

What do we call the genetic make up of the individual, represented by a set of letters? (Ex. Pp or BB or rr)
Genotype
500
How many chromosomes do humans have?
46 or 23 pair
500
Humans pass their genes onto their offspring in this type of reproduction.
What is sexual

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

In a Punnet square, the capital letter represents this.
Dominant trait
