What is Heterozygous
Type of reproduction that is both fast and energy efficient.
When two alleles or genes are different they are called.

**you must name both
What is homozygous dominant and homozygous recessive?
This type of reproduction creates offspring that are genetically diverse.
Sexual reproduction
What is the only way that the recessive gene will be shown?
What is homozygous recessive?
What is an advantage of offspring produced from sexual reproduction?
Offspring have more diversity
Offspring get more advantageous traits

Kendall – Heredity is the study of chromosomes and the genes that they contain.
Carla – Heredity is the passing of genetic information contained in chromosomes from one generation to the next.
Joseph – Heredity is the study of human characteristics passed down from parent to offspring.
Devon – Heredity is the reason that tall parents will usually have tall children.
What is
Carla – Heredity is the passing of genetic information contained in chromosomes from one generation to the next.

What are TT and Tt
Where are your genes found inside of the cell?
Name the tool that we use to help us predict what traits offspring can have.
What are Punnett squares?
Which of the following would produce uniform offspring?

D. An amoeba splits during binary fission into two separate cells.
What is a physical trait that is expressed called? (Hint: a genotype is a gene that is expressed)
Phenotype
Having dimples is a recessive trait. What genotypes would two parents without dimples have to have in order to have a child that does have dimples? Use D for the allele.
Both parents would need to be Dd (Heterozygous)
