Genetics
What is genetics?
The passage of genetic instructions (traits) from parent to offspring.
What is heredity?
Sexual reproduction produces offspring that are genetically _____________ to the parents.
What is different?
Some genes can be hidden or covered up by another. These are considered to be-
What is Recessive?
How are traits passed from parent to offspring?
What is through genes during reproduction?
The biochemical units of heredity that make up chromosomes
What are genes?
Gregor Mendel (describe why this scientist is famous)
Who first studied heredity and the passage of traits from one generation to the next?
Asexual reproduction produces offspring that are genetically ____________ to the parent.
What is Identical?

What is Asexually?
A black chicken (BB) is crossed with a black chicken (BB). What percentage of offspring will be black?
What is 100%?
Why does a Punnet Square use capital and lowercase letters?

Inherited traits that children get from their parents come from-
What are genes?
The physical trait observed in an offspring is known as it's -
What is phenotype?
For some traits, only one copy of a particular gene is needed to show a given trait. These genes are referred to as-
What is Dominant?
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?
What is 25%?

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?
What is 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?
What is Dark brown is dominant and white fur is recessive. Both parents are heterozygous?
