Genetic information
What is DNA?
100
The phase where the cell grows and DNA is copied. This is the longest phase of the cell cycle.
What is interphase?
100
Living thing grows bigger
What is mitosis?
100
How many alleles do we have for each gene? Why?
2. one from each parent.
100
If B is black and b is white, which gene is dominant and which is recessive?
black dominant, white recessive
200
DNA is found in this part of the cell.
What is the nucleus?
200
When chromosomes line up in the middle of the cell.
What is metaphase?
200
Living thing reproduces
What is meiosis?
200
What is a dominant allele?
The dominant allele controls the trait.
200
If R is red and B is blue, and RB codes for purple, then ___ is dominant.
What is R and B.
300
What DNA forms during prophase, looks like and X. Humans have 46 of these!
What is a chromosome?
300
When two new nuclei form.
What is telephase?
300
Makes 4 different haploid cells
What is meiosis
300
What is the difference between genotype and phenotype?
Genotype is the types of genes (alleles) present, and the phenotype is the physical trait (characteristic).
300
If T is dominant for tall and t is recessive for short, then if someone with Tt and TT have offspring, how many of them will be short?
What is 0?
400
The structure of DNA (3 things)
What is double helix, backbone, and bases?
400
When the nucleus disappears and chromosomes form.
What is prophase?
400
Makes 2 identical diploid cells
What is mitosis
400
In classical genetics ___ gene codes for each trait, and there are ___ different versions of an allele.
1, 2

If blue is dominant (B) and green is recessive (b), what is the only genotype that will give a phenotype of green?
What is bb?
500
A small part of DNA that is a code for a certain protein.
What is a gene?
500
When the chromosomes move to opposite sides of the cell.
What is anaphase?
500
Forms gametes
What is meiosis?
