An individual who has two identical alleles for a particular gene is referred to as this
What is homozygous?
100
In a cross between an individual who is homozygous dominant and one who is homozygous recessive for a particular trait, all of the offspring will have this type of genotype:
What is heterozygous?
100
This is the monomer, or building block of the DNA molecule
What is a nucleotide?
100
This is the name of the first step in protein synthesis
What is transcription?
100
Meiosis produces this many cells
What is 4?

An individual who has two different alleles for a particular gene is referred to as this
What is heterozygous?
200
In a cross between two heterozygous individuals, this percentage of the offspring will show the dominant phenotype:
What is 75%?
200
In DNA, A always pairs with this letter
What is T?
200
The first step in protein synthesis happens here
What is the nucleus?

Because they only have half your DNA, gametes are referred to as this:
What is haploid?

If straight hair is dominant to curly hair, a person who is heterozygous for this trait will have this type of hair
What is straight hair?
300
In a cross between two heterozygous individuals, this percentage of the offspring will show the recessive phenotype:
What is 25%?
300
In DNA, C always pairs with this letter
What is G?
300
This is the name of the second step in protein synthesis
What is translation?
300
This is the process by which homologous chromosomes touch each other and exchange portions of their DNA:
What is crossing over?
400
If straight hair (S) is dominant to curly hair (s), an individual with curly hair must have this genotype
What is ss?

If long fur (L) is dominant to short fur (l), and black (B) is dominant to white (b), what is the genotype of a cat who is homozygous dominant for fur length and heterozygous for fur color?
What is LLBb?

For a DNA molecule to replicate, this has to happen first:
What is the molecule must come "unzipped"

The second step in protein synthesis happens here:
What is a ribosome?

Meiosis produces genetic variety through independent assortment and this process:
What is crossing over?
500
If fur color in cats follows a pattern of incomplete dominance, the offspring of a black cat and a white cat will look like this
What is gray?
500
If long fur (L) is dominant to short fur (l) and black (B) is dominant to white (b), how many of the offpsring will have short, white fur if two cats who are heterozygous for both traits have 16 kittens?
What is 1 out of 16?
500
A DNA nucleotide consists of these three parts
What is a sugar, a phosphate, and a nitrogenous base?

During prophase 1 of meiosis, these two special things happen:
