What is the difference between chromatin and a chromosome.

A chromosome is the compacted form of chromatin. 

100

If P (purple) is dominant to p (white), what will the phenotype of a flower with a Pp genotype be?

Purple

100

What equation gives allelic frequencies?

p + q = 1

100

What is density?

The number of individuals in a certain area.
100

What does it mean to be heterozygous for a certain trait?

It means you have two different alleles for that trait.

200

What is an allele?

A variation of a gene.
200

What are reproductive cells (sperm and egg) called?

Gametes

200

What equation gives genotypic frequencies?

p^2 + 2pq + q^2 = 1

200

What is carrying capacity?

The maximum number of individuals an area has the resources to support.

200

How many UNIQUE chromosomes does a normal human cell have?

23

300

In which phase of mitosis does an cell divide its DNA?

Anaphase

300

What is a homologous pair?

Chromosomes with corresponding DNA

300

Why do mutations occur?

They occur randomly.

300

What are the three types of dispersion?

Uniform, Clumped, Random

300

What is the difference between exponential and logistic growth?

A population in exponential growth can continue to grow indefinitely. A population in logistic growth has a carrying capacity.

400

What are the four phases of mitosis?

Prophase, Metaphase, Anaphase, Telophase
400

If Maia is blood type A and Raj is blood type O and they have a child with blood type O, what is Maia's blood genotype?

Ao

400

What does a chi squared test do?

It compares two sets of data in order to determine if the observed data has changed significantly.
400

What are the four Ds that describe populations?

Density, Dispersion, Demography, and Dynamics

400

How many daughter cells are produced from meiosis?

4

500

Does ploidy change in mitosis?

No

500

What is ploidy?

The number of corresponding chromosomes. In humans, since we are diploid, and our chromosomes are arranged in PAIRS, ploidy is 2.  

500

Define evolution, natural selection, and fitness.

Evolution-change in heritable traits over time

Natural Selection-individuals with favorable traits are more likely to survive and reproduce

Fitness-amount of surviving offspring produced by an individual

500

What shape will an age diagram of a population that is undergoing growth take on?

A triangle
500

What is epistasis?

It is when one gene affects the action of another.
