Sexual vs Asexual Reproduction
100
A gene that can prevent the expression of another gene.
What is a dominant gene?
100
The number of pairs of chromosomes that humans have.
What is 23?
100
The form of cell division that creates gametes.
What is meiosis?
100
The offspring genotype for a homozygous dominant parent for curly hair (C) and a homozygous recessive straight haired parent (c).
What is heterozygous (Cc)?
100
Results in offspring that are genetically different from the parents.
What is sexual reproduction?
200
A gene that whose expression is hidden when paired with a dominant gene.
What is a recessive gene?
200
Where chromosomes are found.
What is a cell's nucleus?
200
The type of cell division involved in creating new tissue.
What is mitosis?
200
All possible genotypes for a given trait (ex. tall plants [T]).
What are homozygous dominant (TT), heterozygous (Tt), and homozygous recessive (tt).
200
Results in offspring that are genetically identical to the parent.
What is asexual reproduction?
300
Alternate versions of the same gene.
What are alleles?
300
These are the letters the represent the four bases in DNA.
What are A, T, C, and G?
300
This is the type of cell that results from Meiosis.
What is haploid?
300
The parent that determines whether an offspring is male or female.
What is the father?
300
In sexual reproduction, parents produce gametes that are....

400
An individual that has two of the same alleles for a trait.
What is homozygous?
400
